Catharina de Hertoghe (1410-1467) and Her Descendants in Java, Suriname, South Africa, Denmark, England, India and America
Introduction
Gerrit Ottens and his brother Willem Ottens were born around the years 1425-1436 somewhere near Leerbroek or Middelkoop in the Land of Arkel. Willem Ottens was the various lines in the Netherlands (and in America) with some variant of the surname den Hartog or den Hertog, other lines in the Netherlands, and lines in America named Swaim, although some in America also use the spelling Swain, probably due to the influence of the use of the name Swain by English descendants.
The identities of the parents of Willem Ottens are unknown as neither appears in a document that connects him or her with Willem or Gerrit Ottens. This is probably somewhat odd because both of these brothers owned a fair amount of property, and property transactions were usually entered in books maintained by the lords who owned the land. This lack of records could be because their births occurred during the time of disruption and confusin in the aftermath of the Arkel War, or it coud have occurred to deliberately suppress the facts.
Some people in the Netherlands and now America believe that the father of Willem and Gerrit Ottens was Otto van Arkel, the illegitmate son of Jan van Arkel, the last of the Lords of Arkel. This hypothesis is based on insufficient circumstantial facts that to me aren't convincing, though they are possible. My own hypothesis, which I've previously presented, is that that father of Willem and Gerrit Ottens was Otto Gerrits van Oist, a man who was executed along with several others in 1436 by the government of Utrecht for participating in an armed invasion of Utrecht led by Jan van Arkel Heukelom. I believe that Otto Gerrits van Oist was a member of the van Oist family who at that time were the Lords of Swalmen in Limburg, and that this explains the use of the name Sweym/Swaim by one of Willem Otten's sons and later by Matthijs Barentsen, who had emigrated to New Netherland in 1661, and by most of his American descendants (in Limburg the name Swalmen is pronounced much like Sweym, without the “l” sound or the terminal “-en” sound).
In my post of 24 February 2023 I also stated that I believed the mother of Willem Otens (and presumably the wife of Otto Gerrits van Oist) was likely a woman named Catharina de Hertoghe, lady of Duyst (~1410-1467). This belief was based on her surname, which was essentially the same as the “den Hartog/Hertog” used by various descendants of Willem Ottens, and because she had a daughter by her known husband who had married a van de Werve of Antwerp, and the van de Werve family was somehow closely connected with the Rijswijk Sweym family in Holland (and probably also the smaller Rijswijk in Brabant), and because I've hypothesized that the Rijswijk Sweym family was related to the van Oist Swalmen family in Limburg (we know that the van Oist Swalmens were somehow related to the original van Broeckhuysen van Swalmen family).
My statement that I believed Catharina de Hertoghe was probably the mother of Willem Ottens was a rather bold statement considering the tenuous evidence. I made the statement to provide direction for anyone wishing to pursue it and I originally had no inention of pursuing it myself as I live in America and adequate research would require digging through archives in the Netherlands and Belgium, which I don't have the time or inclination to pursue. However, I've decided to take a look at her background and family connections as presented in the Geni.com and FamilySearch.org family trees, to see if at least those family trees could lend some support to my hypothesis of Catharina de Hertogh as mother of Willem Ottens.
In one sense the examination of hese crowdsource family trees can't even be called “research;” nor can the family trees even be considered true family trees, because the quality of the research that produced the family trees is unknown. A true family tree has to prove each link with documentary evidence proving the relationship, and in most cases this is very difficult to do for more than a few generations, and impossible in most cases for most lineages going beyond the 1600's. This is because the vast majority of people in the past never had their name listed on any document, and if the perosn was not named on a document his existence can't be known. I can't even prove through documentation my own paternal ancestry back to Thys Barentsen. However, I can prove that I must be a descendant of Thys Barentsen through inference to other known Swaim genealogies, to who I'm related through Y-DNA matchinng evidence. This Y-DNA evidence is absolute proof of my close relationship with other Swaims who descended from Thys Barentsen in America, and of my close relationship with the den Hartog/den Hertog lines in the Netherlands. It is in fact stronger proof than documentary evidence because documents can and ofter were purposely forged, falsified or mistaken, whereas Y-DNA evidence at this level is absolute proof (although it can be argueed that the DNA testing companies could have falsified or been mistaken in their test results, but as they have no motivaion to falsify or be sloppy, and in fact motivation to do the oppsite, this is very unlikely. We can argue philosophically that nothing can really be known for certain, but if we go down tha road we might as well not try to make senese of anything at all).
Even though crowdsource family trees have amny drawbacks and can't prove anything, they also very useful if one understands that they're speculative and that the relationships in them have to carefully examined to see if they make sense rather than just accepting them as true. Many people have added relationships based on too little evidence, especially concerning people from before the 1600's. Howver, many of the people and relationships added to these trees were in fact based on documentary evidence of some kind, even if the sources from which the information came were property cited in each of the individual's data page. For example, none of the entries for the de Hertoghe family that I've looked at have any sources listed, in either the Geni tree or the FamilySearch tree. Thus, these people and relationships must be considered speculative. However, I don't believe that the people who added these people to the tree simply made up their names and dates from thin air simply to create chaos; rather, I believe that most or all of this information did come from some source, either primary or secondary, and was based at least on some evidence, even if not on enough evidence to satisfy strict genealogical standards. And this is the great strength of crowdsource family trees—they provide information from thousands of people, some of that information wrong, but probably much of it correct, which can provide a basis for further investigation. For example, if strict genealogical standards were applied to these crowdsource family trees, there would be no information at all about Catharina de Hertoghe; there would simply be no information at all, and thus nowhere to begin a investigation. The research would end as soon as it began because there would be no starting point.
In this post I'm going to study Catharina de Hertoghe's family relationships as presented in the crowdsource family trees, and try to place those relationships in context with the information that I have from my Dutch autosomal DNA matches from MyHeritage.com. I think what I've found is quite interesting, even though it doesn't actually prove anything. Actually, I'm surprised at how well the family tree information of Catharina de Hertoghe's descendants matches the DNA and family tree information of my Dutch DNA matches, specifically about their ancestors who had emigrated to the Dutch colonies of Java, Suriname and South Africa. I've noticed for a few years that many of my Dutch matches appear to have ancestors from those places, and this was especially emphasized since MyHeritage launched their “Genetic Groups” feature in (I believe) 2022. From what I've seen that feature seems to be surprisingly accurate, as opposed ot their even newer “Possible relationships” feature which, although it might be accurate for more recent relationships, in my opinion should be ignored for more distant relationships (for example, my DNA match Ruyters, with whom I share only 1 short DNA segment 8.3 cM in length, is given the highest probability of being my 5th cousin, meaning that our common ancestor was a 4th great-grandparent. Yet this has to be wrong because all of my Dutch ancetry comes from ancetors from New Netherland, who emigrated to America in the 1600's. This means that all of my Dutch DNA matches must have come from a coomn 9th great-grandparent at the very most recent, and most of my Dutch DNA matches and I probably share a common ancestor who lived much further back in time than that, possibly in the 1400's or even earlier).
Who Are the Common Ancestors of my Dutch DNA Matches and Me?
I've previously mentioned that most of the surnames of my Dutch DNA matches don't correspond to the surnames of my New Netherland ancestors. This isn't surprising because, first, in the 1600's in the Low Countries the patronymic naming system was still universal and most people didn't use true surnames—and even those who did use surnames felt free to change them whenever it suited them. And, second, my immigrant ancestors to New Netherland were born in either the late 1500's or ealy 1600's, meaning that more than three centuries (10-13 generations had had passed between their births and my birth. Of my 2,048 11th-generation ancestors, less than 32 (<1.6%) were Dutch. Then, at each generation for the next 11 generations most of that Dutch DNA was randoomly edited out of my chromosomes and replaced with English, German, Irish, Schots, Norwegian, Swedish, Finnish and Icelandic DNA . Based simply on mathematics, I should have less than 2% Dutch DNA.
Yet there's something odd here, because although I have about as much Icelandic DNA as I do Dutch DNA, I have only 14 Icelandic DNA matches whereas I have about 112 Dutch DNA matches, counting South African DNA matches as Dutch (less a few South Africans who have primarily English ancestry). This might be even odder than it seems, because the Icelandic gene pool is small and isolated and thus must be highly edogamous, so that since I'm related to at least one Icelander and I'm likely to be related to most Icelanders, and also my Icelandic ancestry is more recent than my Dutch ancestry. Part of the answer to this situation is probably selection bias, if Icelanders are less interested than the Dutch in taking DNA tests. But I think part of the answer is also even stranger, which is that in fact many of Dutch DNA matches are probably actually Swedish DNA matches. What I mean by this is that I think it likely that many (or most) of my Dutch DNA matches actually come from my mother's Swedish ancestry rather than from my father's Dutch ancestry. This is through the emgiration in the 1500's and 1600's of a number of ancestors from Liege, Limburg, Braband and Holland to Denmark, Norway, Sweden and Finland. Many of the descendants of these emgriants remained in the Scandinavian countries and happened to be my ancetors. I'll demonstrate in a future post how this is true and how I can prove it's true through DNA matching.
Therefore, I've just stated that many or most of my Dutch DNA matches didn't come to me through my New Netherland ancestors! I'd always believed that must be true, but now through my research I'll show that it probably isn't true, that instead many of them came through my Swedish ancestry. This also means that this portion of my Swedish ancestry isn't truly Swedish after all, but is actually Dutch.
However, it really doesn't matter through which country my Dutch ancestors entered my genome; the common ancestors of my Dutch DNA matches and I were still Dutch in culture an in DNA. But it does bring up an interesting question. My paternal line ancestor was Thys Barentsen and he definitely did emigrate from the Netherlands to New Netherland and not through Sweden. But what does this mean for my Dutch DNA with matches with ancestors or collatral who emigrated to Java, Suriname, South Africa, etc. if our common ancestry actually did come through Catharina de Hertoghe? If she was the mother of Willem Ottens, than it could be her DNA that I share in common with many of my Dutch matches. But if this is true, and if many of those Dutch matches are matches that came through Sweden, did I inherit DNA from Catharina de Hertoghe through both Thys Barentsen through my father and also through a Swedish immigrant through my mother? Or was Catharine de Hertoghe not the mother of Willem Ottens and had nothing to do with that family? But she definitely did have something to do with the van de Werve family, which definitely was related to the Rijswijk Sweyms—but were the Rijswijk Sweyms actually related to Willem and Gerrit Ottens' family, just because a couple member used the same name?
This post won't answer all those questions, but whether or not Catharine de Hertoghe was the mother of Willem Ottens, it does seem likely that either she or the van de Werves (or one or both of their families) must have been one of the common ancestors between many of my DNA matches and me.
For this post I'm I have about about 112 DNA matches who are substantially Dutch, which includes the following numbers who now or whose ancestors lived in the following Dutch colonies excluding New Netherland:
South Africa 9
Java/Indonesia 7
Suriname 3
Curacao 1
So that's 20 of 112, or 17% who emigrated to one of these countries (descendants from most of the Java immigrants probably returned to the Netherlands in the 1900's after Indonesian independence).
These are pretty definite statistics because the DNA of the non-South African matches includes at least some non-European DNA that correlates to either Java (East Asian DNA) or South America/Caribbean (African/Central-South American Indian DNA).
MyHeritage's “Genetic Groups” feature also shows something else different but related to this for Java. The Genetic Groups feature looks at a person's DNA and compares it to various populations and assigns that person to the various goups that their DNA resembles. If someone is in a particular “Genetic Group” it doesn't necessarily mean that that person's ancestors actually lived at the location named by that genetic group, but it does mean that he has cousins who live or lived in that location. For example, I've seen various Swedish DNA matches assigned to various North American genetic groups when their family trees show that none of their ancestors ever emigrated to America. In those cases, it would mean that a collateral ancestor (a sibling of an ancestor) did move to those places, even though their own ancestors didn't.
With that in mind, of my 112 Dutch ancestors, MyHeritage placed 35 of them in the “Netherlands and Indonesia (Java)” Genetic Group. This means that 29% of my Dutch Matches have collateral ancestors who emigrated to Java, while at least 20% (7/35) of these had direct ancestors who emigrated to Java.
Altogether, 48 of my Dutch DNA matches are in Genetic Groups indicating their DNA is similar to DNA from the Dutch in South Africa, Java, Suriname and Curacas. This is 43% of my total Dutch DNA matches.
So what does this all mean for our genealogical purposes?
First, because of my small percentage of Dutch ancestry and because of it's generational distance from my birth, it's likely that I only have DNA from only a few of those Dutch ancestors. Thus, the majority of my Dutch DNA matches probably come from one or two of those ancestors, with a few coming from some other of those Dutch ancestors.
Second, the fact that nearly half of my Dutch DNA matches are associated with the Dutch colonies mentioned above means that I can potentiall narrow down the possibility of which ancestor many of my Dutch matches came from. I can narrow it down by studying the family trees of my Dutch DNA matches to find those with ancestors who had siblings who emigrated to South Africa, Java, and the Caribbean.
Catharina de Hertoghe
Here's the line leading down to Catharine de Hertoghe:
Goswin de Hertoghe (1245-) m. Jutta van Eggloy (1250-)(father = lord of Wazembeek)
Willem de Hertoghe (1280-1356 Brussels) m. Beatrix van Eggloy (1280-)
Gilles de Hertoghe (1320-) m. Elizabeth van der Eycken (1335-)
Johan de Hertoghe van Orsmael, heer van Valkenburg (1375-1425)m. Margaretha van Wesel (1380-)
Catharina de Hertoghe, Vrouwe van Duyst (1410-1467)
The father of Julla van Eggloy, who married Goswin de Hertoghe, the first known member of the line, was supposedly the lor of Wezembeke. Wezembeke is located a few miles east of Brussels.
Johan de Hertoghe, the father of Catharina de Hertoghe, was “van Orsmael” and supposedly lord of Valkenburg. Orsmaal is located 34 miles east of Brussels.
Catharina de Hertoghe's mother was Margaretha van Wesel. Given the other Brabant locations, this Wesel was probably Wezel, located 21 miles northwest of Orsmaal.
Catharina de Hertoghe's husband was the lord of Herbais, Huy, and Morkhoven. These are all locations in Brabanteast of Brussels, not far from Orsmaal, Wezembeke, and Wezel.
So we can see that Catharina de Hertoghe's ancestors are from Brabant, including Brussels. This is a problem if we want to place her in the Land of Arkel around 1420-1436. There seems to be no connection to the region of the Land of Arkel or family from that area.
Catharina's father was supposedly the lord of Valkenburg, and there is a Valkenburg that was by 1381 owned by the Dukes of Brabant. This is also very close to Oost and Oupeye, so there's potentially a connection to Dirk van Oist and Felicite d'Oupeye who were at this time the lords of Swalmen in Limburg. Thus, the proximity of this Valkenburg to Oost and Oupeye could explain how Catharina could have been married to Otto Gerrits van Oist.
Furthermore, Oost itself was a part of the Land of Voeren (Fouron), and as I'll show in a later post, if you assume that all the people with the unusual name Steppo from Flanders and Brabant at this time were related to each other, then there would b)e a connection between Steppo van Viggezele of the paternal line of Siger van Gent and Steppo van Maffe, whose brother was the lord of Voeren, which would mean also of Oost (Steppo van Maffe would have been born about 1060).
But I don't think that this was the Valkenburg that Catharina's father was lord of. There is also a Valkenburg in Holland, located about 12 miles north of Den Haag and 5 miles south of Voorhout, which is next door to Teylingen. The reason I believe that this is the correct Valkenburg is because Catharina de Hertoghe was said to be the “Vrouwe van Duyst,” and most people with the name Duyst were called “Duyst van Voorhout.” As there appears to be no Duyst, and as various people named de Hertoghe show up in property transactions in Holland from the 1300's, my guess would be that Catharina's parents had moved from Brabant to Holland sometime in the late 1300's, possibly to escape the Black Plague or war.
(There is also the possibility that the Valkenburg in Holland was named after the larger and more important Valkenburg in Limburg, indicatinng that de Hertoghe had come from there. I actually think this is likely, but lack any evidence for this other than the fact that everything keeps coming back to this region (i.e., Oost and Oupeye with Dirck van Oist (van Swalmen), Steppo and the Lods of Voeren, and this region as the home of many of those who emigrated to Scandinavia)
In one leenkamer entry (20B from DE LEENKAMER VAN DE BURCHT TE LEIDEN, 1256-1744 door C. Hoek Microsoft Word - 1978-080Burcht te Leiden.doc (hogenda.nl) } for 1645 regarding a property in Schipluiden is mentioned a “Jonkheer George de Hertoge, heer van Valkenburch.” What's interesting about this series of entries, from 1515-1645 is that some of the people named were van Matenesse van Foreest, and a “Cornelis van Ghendt, heer van Loenen.” I haven't yet analyzed this entry, but it's especially interesting that a de Hertoghe van Valkenburg was in some way associated with a van Gendt from Loenen, who was possibly a descendant of the Willem van Gendt, ridder, who owned the 28-morgen van Arkel land, some of which ended up in the hands of Willem Otten's descendants. The Geni.com tree places Willem van Gndt as a descendant of the Viscounts of Gent, but this line in the Geni.com tree might be speculative. But in any case, one could make a case from this that Willem van Gendt was the true father of Willem Ottens, not Otto Gerrits van Oist, leaving Catharina de Hertoghe as his mother. I don't think that's true, however.
The Geni tree has the family of “van Duyst van Voorhout” with the paternal line supposedly going back to Ethelred of Mercia (865-), Mercia being in England. This is probably fanciful, but possibly the lines descend from the lords of Beveren in Flanders is true, but this isn't supported by the MedLands site. The Geni tree shows the first ancestor to live in Holland as Alewijn van Leyden, heer van Wassenhoven (1050 Dixmude Flanders-1110 Leiden Holland)(supposedly the son of a Beatrix van Gent).
Supposedly the van Duyst and van Voorhout lines merged with the marriag eof Hendrick Pietersz Nagel van Voorhout (1410-1434) with Immesoet Dirksdr Duyst (1415-1469). If this is true, then Catharian de Hertoghe may have been Immesoet's sister or perhaps cousin. However, these two lines are not connected in the Geni.com tree and I have no idea if any of this is even accurate. If Immesoet Duyst was the sister or cousin of Catharina de Hertoghe, then Catharina de Hertoghe would not be related to the Voorhout line. One interesting thing is that the supposed father of Hendrick Pietersz Nagel van Voorhout is that his father in the tree, Pieter van Voorhout (1340-1390) had supposedly been married to Alijt Willemsdr van Foreest. They had no children, but Alijt's father was Willlem Jansz van Foreest (1326-1396) whose father's sister was Clementia van Foreest who was married to Gysbert Sweym of the Rijswijk Sweyms. Although this is not a genectic connection, it's a social connection to the Rijswijk Sweym family. Another potential connection is that the van Voorhout family in the person of Pieter supposedly married into the Nagel family with Pieter's wife. This would probably be the same Nagel framily of the Willem Nagel mentioned by Moquette in her history of Bulgersteyn that I discussed in my Rijswijk Sweym post. A person named Sweyn lived in Bulgersteyn (in Rotterdam) in the late 1300's, and also a Nagel was involved at around this time with Bulgersteyn.
The upshot of all of this is that it's credible that Catharina de Hertoge had in fact been born in Holland and thus it is much more likely that she could have been the mother of Willem Ottens than if she'd been born and had lived in southern Brabant as much of her background suggests.
Descendants of Catharina de Hertoghe
My hypothesis is that Catharina de Hertoghe was first married to Otto Gerrits van Oist, by who she had the two sons Gerrit Ottens and Willem Ottens, and then in or after 1436 remarried to Simon de Dammartin. If this was true, then her children by de Dammartin woud be half-siblings of Willem Ottens and the descendants of those half-siblings would have her de Hertoghe DNA which would match the DNA of the descendants of Willem Ottens if both descendants had inherited such DNA.
The following all assumes the accuracy of the Geni.com family tree. I haven't verified the accuracy of even a small part of this tree, so that's an issue. But since by using this tree I'm going to show that the emigration pattern of Catharina de Hertoghe's descendants matches that of many of my Dutch DNA matches, Catharina de Hertoghe's DNA might be the source of the DNA in common between many of my Dutch DNA matches and me. This, however, is complicated by the fact that all of these descendants of Catharina de Hertoghe are also descendantss of the van de Werve family though the marriage of Catharina's daughter to a van de Werve. Since the Rijswijk Sweym family had definitely married into the van de Werve family, and since the Rijswijk Sweym family is likely to be related to the descendants of Willem Ottens, the common DNA between my Dutch matches and me could be van de Werve DNA rather than de Hertoghe DNA. And f it's the case that the common DNA is van de Werve DNA, then it could have come through someone other thatn Catharina de Hertoghe (e.g., from a van de Werve living in the Land of Arkel in the early 1400's through someone other than Catharina de Hertoghe).
However, I have not seen a convincing explanation in the crowsource family trees of why so many of my Dutch DNA matches are descended from those who had emigrated to Jave, Suriname and South Africa except through Pieter van de Werve and Catharina d'Herbais, the daughter of Catharina de Hertoghe. And, as we'll see, the family tree of one of my Dutch DNA matches with Dutch-Java ancestry strongly points to descent from this couple.

To simplify this family tree:
Catharina de Hertoghe (1410) married Simon de Dammartin. Dammartin's ancestry is irrelevant to us because presumably my Dutch DNA matches and I don't descend from him but rather only throug Catharian de Hertoghe though a previous marriage.
Catharins de Hertoghe's daughter married Pieter van de Werve of Antwerp. Pieter van de Werve's granddaughter Marguerite married Henri de Coninck (1480) of Antwerp. The de Coninck family went back to Arnould I de Coninck (1200-1261) of Brussels.
Cathara de Hertoghe's DNA remained in the de Coninck paternal line for 4 generations to Francois de Coninck (1621-1662) who married Catherine Crommelin (1632-1694); Crommelin's ancestry goes back to Ingelmunster, Flanders in the 1400's.

(Note the interesting name of the death place of Abraham Camin (1754): "Suikkerrietplantage Fauqueberg"' This means "Sugar plantation Valkenburg," the name of which appears to be a nod to their de Hertoghe ancestors who were the lords of Valkenburg (and possibly still were).)
The above genealogy includes up to 4 generations of descedants of he siblings Catharina de Coninck and Frederic de Coninck, but doesn't include all of the people in the Geni.com tree for those three generations; I left out several from England and the Netherlands who were redundant for our purposes. Also, the Geni.com tree is probably incomplete and doesn't show the descendants of several of the family who had moved to Suriname and Java simply for lack of knowledge (e.g., no descendants are shown in the family tree for Ester de Coninck (1696), who had married Louiis de la Croix; this doesn't necessarily mean that Ester and Louis had no descendants, but could alternatively mean that the person who posted this genealogy had no knowledge of those descendants).
I've shown the descendants of Catherine de Coninck (1694-1741) in italics because these are the same people as the descendants of Abraham Camin (1694-1741). This is because Caherine and Abraham were first cousins, both sharing the same set of grandparents Francois de Coninck (1621) and Catherine Crommelin 1632).
I should also point out that Francois de Coninck (1621) and Catherine Crommelin (1632) had at elast twoother children who survived into adulthood whom I didn't include because the Geni tree doesn't show that they had and descendants. But this may simply be due to ignorance of those descedants, so I'll include them below because in fact they may have had descendants and those descendants may have remained in the locations listed as their places of death. This could be especially relevant for Jean de Coninck (1662-1690) becaue he was married and he died in Rotterdam, and as we'll see next the large majority of my Dutch DNA matches were placed by MyHeritage in the “Rotterdam” Genetic Group; if some of the descendants of Jean de Coninck (1662) were used as Rotterdam reference populations for the determination of Genetic Groups, this could explain why so many of my Dutch matches belong to the Rotterdam Genetic Group.
Francois de Coninck (1657-1695) Rouen, Normandy, France
Jean de Coninck (1662-1690) Rotterdam, Holland
Albert de Coninck (?) ?
When I began looking into the descendants of Catharina de Hertoghe, I had no idea that so many had emigrated to other countries, but this immediately interested me because I knew that many of my Dutch DNA matches were associated with Java, Suriname and South Africa. I'll discuss this in more detail later, but while we're here I'll make a list of the places that the descendants of Catharina de Conninck (1655) and Frederic de Conninck (1660) emigrated to.
Italy
England
India
Suriname
Curacao
Indonesia
South Africa
Denmark
USA
This is a pretty remarkable diaspora of the descendants of Catharina de Hertoghe during the 1600's and 1700's, and could possibly account for all of my DNA matches who belong to the “Java”, “Suriname”, “Curaca”, and “South Africa” Genetic Groups as predicted by MyHeritage.com, much of which is supported by MyHeritage's DNA predictions from those regions as well as genealogies (there is obviously an organized effort on Geni.com by Dutch South Africans to develop their genealogies, which can be identified by the designation in a person's page “SV/PROG” (an acronym for Stamvader Progenitor)
Next we'll look to see if we can find any DNA evidence among my Dutch DNA matches that could tend to confirm that Catherine de Hertoghe was indeed an ancestor to any of them. This would not necessarily mean that any of them were descendants of Catherine de Hertoghe and Otto Gerrits van Oist, assuming that those were the parents of Willem Ottems; rather, it could simply mean that they shared de Hertoghe (or de Coninck or Camin, etc) DNA through some other relationship. The point is that if an of my Dutch DNA matches have any relationship at all to the genealogy above, it increases the likelhood that I'm related to them through Catharine de Hertoghe (or possibly her son-in-law Pieter van de Werve).
And, as we'll see, the above genealogy may indeed explain why so many of my Dutch DNA matches have a connection to Javea and/or Suriname
DNA Evidence
When we look at my DNA matches to see if we can find any evidence that any is related to the above family groups, we should understand what it is we're looking for.
My hypothesis is that Catharina de Hertoghe was the mother of Willem Ottens. Even if that hypothesis is true, this doesn't necessarily mean that any of my Dutch DNA matches are also her descendants. But some could be. Few if any of them will probably also be descendants of the father of Willem Ottens (hypothetically Otto Gerrits van Oist) because most of those will have the name den Hartog, den Hertog, van Deventer, Swaim, or otherwise have connected their more recent trees to the tree developed by H. den Hertog as mentioned a number of times in previous posts. Or some might have, for example, DNA from a Coninck or Camijn or some other person in the above genealogy.
So here's how the DNA flow would go in this scenario. We're hypothesizing that Catharina de Hertoghe was first married to Otto Gerrits van Oist. In this scenario she had two children by van Oist, Gerrit and Willem, and when they were young in 1436 van Oist was executed for taking part (and being caught) in Jan van Arkel Heukeom's raid on Utrecht. Catharina de Hertoghe then remarried to Simon van Dammartin and went to live in Antwerp, either leaving her two sons in the care of relatives in the Land of Arkel or taking them with her and they returned as adults because owned property there. Catharina de Hertoghe subsequently had two children by van Dammartin, a female and a male. The female married Pieter van de Werve of Amsterdam and left descendants as in the above genealogy.
But Catharina de Hertoghe's son also left descendants, and this gives us a further opportunity to possibly detrmine the true source of the DNA among the descendants of Catharina de Hertoghe. That is, even if we can conclude from DNA evidence that Catharina de Hertoghe's descendants are related to my Dutch DNA matches, this doesn't prove that they came from her because they could instead (or in addition) have come from Pieter van de Werve. This is because the van de Werve family is somehow closely related to the Rijswijk Sweym family, which may be closely related to the van Swalmen farmily of Limburg. We don't know for certain this is true, but I've hypothesized that it's true. However, Catharina de Hertoghe's son was not related (or at least not closely related) to the van de Werve family and thus if we get a strong DNA signature from the descendants of Catharina's son, then that must come from her DNA rather than from van de Werve DNA.
Regarding my Dutch DNA matches, I have no idea how I'm related to most of them. A couple have a Couwenhoven or Cool, or some other person with onen of my ancestral surnames, and the odds are good that indded I'm related to these matches through one of these ancestors. But for the majority of my DNA matches, I don't have a clue and this is no surprise because our common ancestors will have been born in 1500's or before, may not have had a surname, and could have come from Holland, Gelderland, Limburg, Brabant, Hainaut, Flanders, Zeeland, Liege, or one of the small counties and so on. Autosomal DNA travels widely, especially among the nobility in the Middle Ages and after that especially during and after the Reformation when Catholics and Protestants were mving around to avoid being ostracized or murdered for the religion they practised.
What I did was to search the family trees of my Dutch DNA matches for people with the surnames in the Cathrina de Hertoghe genealogy. None have Catharina de Hertoghe herself in their family trees, which is no surprise even if she was Willem Otten's mother because if that's true it's been kept a secret. But the other surnames might crop up through more recent connections that nobody has traced by to Catharina de Hertoghe, so it may be possible to find soome of these surnames in the family trees.
Considering how few of my Dutch DNA matches have large family trees, I didn't expect to find many of the target surnames in their family trees, and I didn't. However, I did find a couple, one especially interesting, and one (Molle) in the tree of one of my American DNA matches from Ancestry.com. Here they are:
Molle
I have a DNA match in Ancestry (12 shared cM, l segment) who has an ancestor born 1852 in “Grand Hallet, Liege, Belgium.” Grand Hallet is located only 9 miles from Orsmaal. Molle is supposed to have died in Zandhoven, located 44 miles from Grand Hallet (and 6 miles from Ranst, of whom the Berthouts were lords). I have no known connection to this DNA match, although of course I could be related to her through some DNA other than from Molle.

Coninck
MyHeritage Dutch DNA match Waslander has in her family tree a Leuntje Klass Coninck (1675-1746), born in Ter Heijde in South Holland, died in Scheveningen. I have other DNA matches with Scheveningers in their trees (e.g. Pronk, Plugge, etc) and yet no ancestors who ever lived in Scheveningen. It's possible that Leuntje Coninck's relocation to Schevening might be the source of (de Hertoghe?) DNA there.
MyHeritage Belgian DNA match de Clerck in his family tree a Balduinus de Coninck (1620-) born in Sint-Niklaas located 14 miles from Antwerp. Henri de Coninck (1480), who was married to Marguerite van de Werve, was born in Antwerp.
Camin/Camijn
Ancestry.com DNA match with 8 cM shared DNA probably has a Camin in his family tree but his tree is private.
MyHeritage Dutch DNA match Patrick has in his tree Agnita Huberta Camijn, his 4th great-grandmother, born 1792 in Ravenswaaij. This must be the same person as the Angenita Huberta Camijn (1792-1830) in the Geni.com tree, who was a daughter of Jean Camijn (1750-1820). Jean Camijn's grandfather (and thus Agnita's great-grandfathers) was Abraham Camijn (1697 Rotterdam-1741 Suriname).
.png)
Thus, Catharina de Hertoghe was Patrick's 17th great-grandmother.
This assumes, of course, the general validity of this part of the Geni.com family tree, but the fact that Pare connected by DNA and that we have this connection through the Geni tree is strong evidence that the tree is correct. This is a plausible pathway for the DNA that I share with Patrick.
However, it is of course possible that the DNA came through some other line, and even if it came through this line there's a strong possibility that it came from the van der Werve line rather than the de Hertoghe line. Thus, this connection to Patrick doesn't really prove that Catharina de Hertoghe was the mother of Willem Ottens, although it is certainly consistent with that hypothesis.
Patrick is in both the Suriname and Java Genetic Groups and has non-European DNA consistent with Suriname ancestry. Assuming the correctness of the Geni.com tree, this is a direct connection from Patrick up to Catherine de Hertoghe, and is strong evidence that the DNA shared by Patrick and me, and possibly by many or most of my other Dutch DNA matches, is DNA from Catherine de Hertoghe (or possibly from the van der Werve line).
Genetic Groups and Non-European DNA
When I posted my 24 February 2023 on Siger van Gent and Oda Berthout van Grimbergen and mentioned that Catharina de Hertoghe was probaby the wife of Otto Gerrits van Oist and the mother of Willem Ottens, I had only looked very briefly at her (supposed) genealogy and hadn't known that several branches of her descendants had emigrated to Jave, Suriname, America, and Denmark-Norway. When I finally looked more closely at her genealogy on Geni.com and saw that many of her descendants had emigrated to those locations, this immediately alerted me because I knew that MyHeritage had claimed that a large number of my Dutch DNA matches had DNA that matched their DNA for their “Genetic Group” called “Netherands and Indonesia (Java)”, which MH further explains means “Dutch and Indonesians in Netherlands and some in Indonesia (Java)”. Fewer of my DNA matches, but still a significant number, are in the groups indicating an association with South Africa, Suriname and Curacao, like Java all former colonies of the Netherlands. A large percentage of my Dutch DNA matches also have DNA matches in Denmark and Norway.
Thus, descent from Catharina de Hertoghe could explain all of my Dutch matches who match the above Genetic Groups predicted by MyHeritage. I also realized in fact such a scenario in which most or all of my Dutch DNA matches in these colonial Genetic Groups stem from one ancestor makes more sense than if they had come from several ancestors. This is true because so many generations have passed between my Dutch DNA matches and myself; the ancestors of all of my Dutch DNA matches must have been born before about 1600 AD, and for most of them probably well before—thus, it's more likely that I'll only have identifiable DNA from only a few of my Dutch immigrant ancestors rather than many.
The chart below shows my current list of Dutch DNA mathches along with the amount of DNA in cM and the number of DNA segments that we share. Also I've indicated which of the matches was placed by MyHeritage in the indicated Genetic Groups. Most matches belong to several different Genetic Groups, so for each match this is only one or a few of the Genetic Groups in which MyHeritage placed them.

Thus, MyHeritage claims that a whopping 35% of my Dutch DNA matches are matches to the genepool composed of Dutch who emigrated to Java or who actually have any amount of DNA that indicates probable Indonesian ancestry.
And 49% of my Dutch DNA matches have DNA similar to that of the Dutch who were present in Java, combined with those similar to the Dutch who were present in Surinam, Curacao and South Africa.
As we've seen, these are all places that descendants of Catharina de Hertoghe had emigrated to.
I haven't seen any other ancestor or potential ancestor that fits this emigration pattern so closely as that of Catharina de Hertoghe. Even so, this isn't proof that this DNA came from de Hertoghe or van de Werve; it's only evidence. However, overall I think it's strong evidence—very strong evidence considering Dutch DNA match Patrick's family tree connecting to the Camijn family.
Update 13 June 2023
The day after publishing this post I returned for a different reason than Catharina de Hertoghe to the Hofstede Arkel leenkamer entries (Microsoft Word - 1984-196Arkel-Land van Arkel.doc (hogenda.nl)), specifically to what J.C. Kort listed as #54, the 28-morgen property in Lang Nieuwland in the Land of Arkel. This was a special property because it was declared to be free from any claims from any third party and it was where Jan van Arkel had held his daily gerecht, probably meaning where he made public decisions, rendered judgements, and so on. I've mentioned this property a number of times but hadn't looked at it in more than a year.
This property in 1413 had been sold to Willem van Gent (ridder) by “Jan van Herlaar van Meerwijk”. I don't want to become tangled up here in the issue of Jan van Arkel and his troubled end, but it appears that Jan van Herlaar was the father of Willem van Gent's wife Gerarda (and Gerarda's maternal grandmother was Cunegunde van Arkel, the daughter of Jan van Arkel Bishop of Utrecht and Prince-Bishop of Liege (1314-1378)). Thus, Jan van Herlaar transferred the 28-morgen property to his son-in-law Willem of Gent, probably after obtaining it from Count of Holland after Jan van Arkel had lost control of his lands.
The presence of Willem van Gent here raises a lot more questions than when I first analyzed the property transactions of this 28-morgen property because at that time I hadn't developed the hypothesis that Seger van Broekchuysen was actually Siger van Gent. I don't know how Willem van Gent fits into this equation, but it's possible that he, and not Otto Gerits van Oist, was the father of Gerrit Ottens and Willem Ottens. He was obviously physically present or potentially present in the Land of Arkel at the right time, and as he apparently died in 1437 or 1439 he had lived long enough to father the two brothers. In this case the patronym “Ottens” would have been a deception, but given the complicated and dangerous politics at this time, such a deception wouldn't be surprising. Also, if he was related to the van Swalmen family, which presumably he would be, this would explain why the name Sweym was later used by his descendants.
I don't think that Willem van Gent was the father of Gerrit and Willem Ottens, but I have to put this forward as a possibility. However, he isn't the reason I'm bringing up this 28-morgen property in this particular post.
Willem van Gent or a son named Willem sold the 28-morgen property to Jan Knobbout Hendriksz in 1451. In 1487 the property pased to Hendrik Knobbout “de oude” on the dath of his father Jan, and in 1493 it passed to Hendrik's son “jonge” Hendrik Knobbout vn Os. A few years later the land was subdivided into 5 properties, labeled in the leenkamer presentation as 54A through 54E.
The reason for this update is because of the name of one of the later owners of 54a, a man who obtained the property through inheritance on 6 July 1562. This was Frans Duyst Dirksz van Voorhout. This name meant nothing to me when I first looked at this property, but of course now I know that he must have been related in some way to Catharina de Hertoghe, vrouw van Duyst. In other words, there is in fact a strong connection between Catharina de Hertoghe and the Land of Arkel, and not only just the land of Arkel, but the 28-morgen land special to Jan van Arkel, other parts of which were also owned at this time by Adriaan van Megen and Willem van Megen.
In other words, the chance that Catharina de Hertoghe was the mother of Gerrit and Willem Ottens just increasted significantly. This is because this occurrence of a Duyst as an owner of one of these 28-morgen properties is associated with the descendants of Willlem Ottens independently of my association of Catherina de Hertoghe with the descendants of Willem Ottens. This is because when I first considered Catharina de Hertoghe a possibility as Willem Ottens' mother, I didn't know that Frans Duyst van Voorhout was associated with the 28-morgen property (I had surely seen his name when first looking at the leenkamer entries is late 2021, but had forgotten it as the name had meant nothing to me).
However, although it seems likely that Frans Duyst van Voorhout's later ownership of the subdivided unit 54A is related to the probable earlier ownership of that land by Catharina de Hertoghe, it looks as if it might be difficult to establish a direct step-by-step connection between Catharina Duyst and Frans Duyst.
In 1562 “Frans Duyst Dircksz van Voorhout, burgermeester van Delft, te den Haag” took ownership of the 17-morgen 54A property through the death of “mr. Michiel Menninck.” As he appears to take ownership through operation of law rather than through purchase, he must have inherited the property. In the Geni.com tree Frans Duyst (1500-1573) is shown as having a daughter, Johanna (1530-1612) who married Adriaen Michielsz Menninck (1533-1595), the son of Michiel Adriaensz Menninck (-1562). These entries in the tree probably came from the information in this leenkamer, but as sources weren't provided it's possible they came from elsewhere.
In the preceding 1560 entry, Michiel Menninck is described as a priest and a canon of Gorinchem. In that entry Michiel got the property by “overdracht” (transfer) from Adriaan Menninck.
(Adriaan Michielsz Menninck (married to Johanna Duyst) has a street named after him in Den Haag (Menninckstraat). The Dutch Wikipedia article “Lijst van straten in Den Haag” says that he was a “watergeus,” a term that usually translater as “sea beggar.” The Wikipedia atricle “Geuzen” says that this “was a name assumed by the confederacy of Calvinist Dutch nobles, who from 1566 opposed Spanish rule in the Netherlands. The most successful group of them operated at sea, and so were called Waterguezen....”Water Beggars....” It also says he was a “mitten-cutter, cloth-dyer, iconoclast and privateer captain.” (Google translation). This street named after him is in Scheveningen, which is a district of Den Haag. There is also an “Adriaan Menninckkwartier” district in Utrecht.)
There are a couple previous entries that I don't completely understand, but the property first came into the hands of “mr. Michiel Menninck Adriaansz., priester” in 1536 by transfer from “Gijsbert Andriesz. Voor Dirkje, diens vrouw” (which mens that Dirkje was the wife of Gijsbert Andriesz, not of Menninck.
The previous entry from 1535 further clarifies the identity of Adriaan Gisbert Andriesz, as he is named “Gijsbert Andriesz. van Arkel” and his wife as Dirkje Bertoutsdr. And the first entry of 1499 identifies the father of Dirkje Bertoutsdr as Bertout Dirksz., who obtained it by transfer from Hendrik Knobbout van Os.
The problem here is that Frans Duyst van Voorhot only seems to have received th property in 1562 through the marriage of his daughter to Adriaan Michielsz Menninck, and that he didn't have a prior claim to the property. But then why did he get possession of the property at all on the death of Michiel Menninck rather than Michiel Menninck's son? Was there some prior interest that he owned?
If we assume that Otto Gerrits van Oist was the father of Willem Ottens and Catharina de Hertoghe the mother, and that they lived on the 28-morgen property, then while they lived on the property it would have been owned by Willem van Gent, who owned it from 1413 to 1451.
The exact connection between Catharina de Hertoghe and Frans Duyst van Voorhout is elusive but probably somehow exists. This should be further researched.
This is a good place to point out another direction for research is the connection between the van Gent family (i.e., the Willem van Gent family of Gelderland) and the Brimeu family. This is of interest because the Brimeu family were the Counts of Megen, and the name van Megen was used by Adriaen Willems de Backer (AKA Adriaen Willemsen den Hertoch, Adriaen Willemsen van Megen.” (This line also owned land in the 28-morgen van Arkel property).
