DNA mapping by People of the British Isles project (General)
The idea of a unique genetic sub-set in the FOD is borne out by my having only 57 exact matches to my Y-DNA at the 12 allele level.
On the other hand, out of these matches 61% have Welsh names (Jones, Davis, Jenkins, Lewis and Williams) which are also very common in Wales.
Perplexing.
I have traced my ancestry back to 1640 in the FOD.
