G-FGC6618

This clade arose 8200 years ago.
It has not branched out for more then 7000 years. (1)

According to older branches, the ancestor of this branch lived in Anatolia. Here lay the cradle of many G clades.

In Roman times one of his descendants sprouted three side branches at the same time. Because all of them live in the Maasdal, he must have lived here. It is quite possible that he arrived here in Roman times and a Roman legionary.

Three families descend from him: Marres and Slootmaekers and Nolet. The first two have lived in Maastricht for many centuries, the Nolet family in Namur. All three are in the Meuse valley on the northern border of the former Roman Empire.

In the Marres family it was first established that the DYS19 can have a double equal value. Here DYS19 = 15 - 15. (3)

The STR tree of the Benelux group
Genogram-Marres-Mares-Nolet-Slootmaekers

In the family Marres G and B have a common ancestor five generations ago. They both have one single mutation. Expect is also 1 to 2.

In the family Mares, A and G have a common ancestor 10 generations ago. A has 4 mutations and G has 3. It is expected here 3 or 4. This fits nicely.

The branches Marres and Mares have a common ancestor 15 generations ago. The number of mutations is, respectively, B 2, G 2, A 4, and G 3 mutations. It is anticipated here 5. This is clearly at all less then expected.

The families Marres, Nolet and Slootmaekers have a common ancestor that lived between 30 to 60 generations ago. Counting STR mutations over such a long time is irrelevant because of convergence, what means parallel and reverse mutations. We will see a seemingly small number of mutations and a seemingly minor genetic distance.

In black the Genetic Distance. In green the number of markers used.

We can see that using STR mutations are useful for dating genetic distance between samples up to about 1000 years ago, but earlier than this, accuracy falls away, and using SNPs becomes the more reliable method.
