This project is for people who have tested and been assigned the paternal haplogroup R-U106 (Y-DNA) and also for people who are believed to have been this paternal haplogroup based on tests done on descendants.

The current naming convention is to use the terminal SNP, so R1b, U106* Also known as R1b1b2a1a (S21+), previously known as R1b1b2a

From The R1b1b2a1 (S21+) is a prominent R1b subclade and is likely the major subclade in resolving identity after the R1b1b2 (M269+) subclade.

From "R1b1b2a1a (S21+), previously known as R1b1b2a Unusually short DYS458 alleles (DYS458.2) are associated with R1b1b2a1 (S21, aka M405). Cases of this allele have so far been detected in Ireland, England, Germany, the Netherlands and the U.S. (1-5%) and this appears to a unique west European marker. The DYS458.2 allele also occurs independently in the Y-chromosome J1 subclade. "

Probably Germanic tribes, Frisians, Anglo-Saxons


From "....frequency is highest in the Dutch (35%) and it is also rather high in England, Germany, Austria, Denmark, Czech Republic and Switzerland (13-23%). This region overlaps origins of Germanic groups, such as the Anglo-Saxons in Frisia. It does not appear to have extended its reach beyond West and Central Europe (except recent migration to the USA)"

Famous Members

Update October 9, 2013: Using DNA samples from three living members of the House of Bourbon, a new study shows the family belonged to R-Z381* (a subgroup of R-106), not G2a. See Dienekes Anthropology Blog, House of Bourbon belonged to Y-haplogroup R1b1b2a1a1b* (R-Z381*), Oct. 9, 2013.
