The Family Clade

The ancestor of our family is Morech, citizen of Maastricht and landowner in the seigniory Zussen. He is mentioned for the first time in the year 1388.

It is with his great-great-grandson Reyner Marres II (1490 - 1553) that our family splits into two branches Marres en Mares.

One member of the Marres branch and two members of the Mares branch performed a full Y-DNA test. From the first human being to Reynier II, every family member owns the SNPs obtained until then.

An SNP occurs on average once every 150 years. From the number of acquired SNPs, it is therefore possible to estimate the length of time to the first common ancestor with the two other branches from the FGC6618 clade, the families Nolet and Slootmaekers.

Researchers from YSEQ and ISOGG found the following SNPs that we obtained since this branching. The name is a letter number combination that the laboratory gives it. Sometimes there are alias names, then more laboratories dispute the discovery. Found are: FGCC6629, FGC6631, FGC6633, FGC6634, FGC6645, FGC6651, FGC6688, FGC6706, Y30008, Y135620 aka MF8691.

The researchers at YSEQ found two more extras: Y30008 and Y135620 aka MF8691.

This number of 8 to 10 SNPs stands for a duration of 1200 to 1500 years. The branch of the other two family in the Benelux therefore took place in the late Roman period or the beginning of the Middle Ages.

The ISOGG named our clade in its Y-tree FGC6629 . YFull opted for FGC6634.

The Moorrees family, from Eijsden near Maastricht, is, according to a genetic test done to one member of their family, not related to us. (1)

Maastrichts charter betreffende belasting vrijdom voor de gebroeders Matthijs, Jan en Reijner Marres, 8 augustus 1526

At the sons of Reijner Marres II (1465-1530) the family splits into the branches Marres and Mares.

On the left is the image of a charter from the year 1526 in which the two brothers, Matthijs and Reyner, are mentioned together with a third brother Jan from whom no branch came. In this charter, the magistrate of Maastricht confirms their free trade in the duchy of Brabant, the area of which Maastricht was a part of at the time.

The Family Y-DNA clade

Four centuries have passed since the split into two branches, to be precise fourteen generations. You expect two to four SNPs. These are then divided into best, acceptable, ambiguous and low quality.

Mitochondrial DNA

In the mitochondria of the body cells of all living things there is a relatively small amount of DNA. This comes from the female egg cell. It is thus passed on by the mother to sons and daughters, but only daughters pass it on, the sons do not. The Mt DNA in a family therefore varies per household. It is determined in our family member E.C.W.L. Boed Marres.

The ascending line goes from his mother over the families: Franquinet, Tielens, Corten, Becker, Geurts, Meyers, Peussens, Claessens, Deumans, Brants, Limpens, and so finally to the oldest known foremother Margaretha Geelen, born around the year 1570 who lived in Schinnen, South Limburg, 15 kilometers northeast of Maastricht.

Mt DNA is also divided into haplogroups by analogy with the Y-DNA, although they are biochemically rather different. The haplo group is I1a1*.

Autosomal DNA is the total DNA of all chromosomes and comes from all ancestors. It gives a picture of the origin of the joint ancestry. (7)

B.M. K36 Ancestry Report Geografcal 2018-800

With the mouse on the map there is an enlargement and green dot on Maastricht.

My genome has common genes with mainly West Germans, starting with the people of Hessen and Baden-Württemberg, then mainly South Germany and Switzerland, followed by the Walloons, Northern French, Lorraine, Flemings and finally Englishmen from the South-East.

In the first millennium of our era and perhaps even before, many peoples went from East to West Europe. And many residents of what is now the Netherlands, Belgium, Westphalia and Saxony went on to Great Britain. Many of course also lagged behind.

My ancestors came all from regions more southerly than Maastricht. Striking is the lower share of Limburgers. Brabanders are poorly represented and the other Dutch are hardly there. When many use their genome for research in this way, this will make European migration history more clear.



This is a group of geneticists who carry out the autosomatic tests for the large companies. They searched for origins from thousands of years ago with the original inhabitants of Eurasia.

The oldest are the Altaic natives who stayed here on the tundra during the ice ages. After the ice ages around 10,000 years ago the hunter-gathererers who repopulated the European mainland from their refugia on the Mediterranean. The Neolithic farmers came from Anatolia 7,000 thousand years ago, and the Corded ware people Iron Age people arrived from the Caucasus 5000 years ago. The Huns also have some left traces.

Etnische herkomst B. Marres, Bron: GedMatch


Gedmatch compared our family DNA with archaeological remains of hunter-gatherers and the first European Neolithic farmers. Below is a figure with the results in order of the established relationship with whom we share at least one CentiMorgan, a measure of kinship. (8)

In archaeogenetics, 1 cM is the lower limit for kinship. The higher this number is, the greater the kinship, so with more and thicker lines.

In the table below we are the most related to two Neolithic persons who lived 7200 and 3200 years ago in what is now Hungary. They are closely followed by a 7000-year-old discovery from Stuttgart, then a Luxemburger from 8000 years ago. Then a 45,000 year old find from Siberia and a North American Indian from 12,000 years back. His ancestors must not have crossed the Beringbridge not long before that time.

Striking is the large genetic distance to English, Scandinavians and Spaniards Here we seem to have hardly any common ancestors. The least we are related to a Brit - at the very bottom - with whom we share segments of 1 or 2 cM in five places.



Neanderthal genes

A nice test is the presence of Neanderthal genes. Our quantity is estimated, depending on the testing laboratory, between 2.8% and 4.8%, of which about 2/3 come from Neanderthals and 1/3 from another pre-modern human species, the Denisovans.

The family DNA Marres

At the International Congress for
Genealogical and Heraldic Sciences
held in Maastricht in September 2012

At this Congress Dr. W. Penninx pronounced the opening lecture. He discussed the variants in the Y-DNA of the various branches of the Marres family and how small mutations in the Y-DNA can show near and distant family relationships, which is impossible to do with only genealogical and historical research.

He shows familial relationships that go back to the Middle Ages and even to the Neolithic. The results of the DNA tests in the Marres family serve as an example.

The motivation for launching the genetic study was our goal the expected but not yet proven genealogical relationship between the Dutch Marres and Mares families, if not to prove then at least with a maximum of security to make plausible.

Genetic Variation in the Last 2000 Years

It has always been assumed that the Maastricht families Marres and Mares were two branches of one family. We were able to demonstrate this relationship with DNA research.

When this goal was achieved, we used the genetic knowledge built up by this to find out our family history until prehistoric times. With the collected facts we hope to contribute not only to the national history of our country but also to the European and world history.

Many publications have appeared in the genealogical and heraldic magazines about the Marres family. In one of them, De Nederlandsche Leeuw of 1990, the common origin of the Marres and Mares family has been made plausible. (10)

The rise of the DNA research in this century offered a wonderful method to prove the supposed relationship. Four men from the Marres and Mares families participated in this genetic family research and did DNA tests: Boed and Gilbert Marres, and André and (the late) Guus Mares and participated in several projects.
