Genetic Genealogy

A number of years ago National Geographic aired a program on the migration of the human race out of Africa, and it caught my imagination. It was the first time I had ever considered genetic ancestral testing.

As a result of that program my father was nice enough to provide a cheek swab and send it to a lab for processing. While my father tested for both paternal and maternal genetic origins, it is the paternal line that is of interest to me and to the rest of the family as we share common paternal ancestry.

Drumroll please. Any the Haplogroup is.... no big surprise.

The de Büren Family Hapolgroup on the male side in R1b, the most frequently occuring Y-chromosone haplogroup in Western Europe.

Within haplogroups are subclades or more precise genetic markers and the subclade for the de Büren family is R1b1b2a1a1 (R-U106). It represents over 25% of R1b in Europe. It is highlighted below in yellow.


In Europe, the subclade (including its own subclades) has a distribution running north west to east and is found in higher concentrations in England (21.4%) and Scandinavia (Denmark 17.7%), reaches a maximum in the Netherlands (37.2%) and slopes down to the east through Germany (20.5%) and the Alps (Switzerland 13.3%, Austria 22.7%) towards the Czech Republic (13.9%) and Ukraine (9.4%). Towards North-Eastern Europe the concentration goes down to 8.2% in Poland and 7.2% in Russia. The subclade appears to be omnipresent in Europe, although it becomes less pronounced in Ireland (5.9%) and France (7.1%) and, further towards the Mediterranean, low values are measured in, Italy (3.5%), and Turkey (0.4%). The frequency of this subclade remains unknown in certain parts of Europe such as Iberia and the Balkans.

The age of U106 is around 3,100-3,900 years old.
