Hi Mike, I will separate out the people in the R1b1b2a1b Subgroup of the Ireland yDNA Project as L21- or L21 unknown and I will ask those members to join the R-P312 and Subclades Project. I will also suggest they on the SNPs you mentioned in your message. Thnaks for the advice! Regards, Margaret Jordan > Project Administrators: > > 1.
