The marker is DYS570, a single copy marker. FTDNA returned a value of
14 for this individual but his three distant cousins are DYS570 = 17.
FTDNA has since confirmed the validity of the 14 and the three 17
values. Their haplogroup is R1b1c (M269+). Their known MRCA was born
ca 1750 and, aside from this marker, they have a max GD of 2 at 67
markers.
