Internet web pages claim that the French ancestry of the Richard Fancher family (NJ, VA/NC, TN, AR) has been disproven by DNA research. Fancher data posted online shows a predominance of R1b1b2. Someone has apparently interpreted this data as disproving the possibility of French ancestry.
I am not a geneticist or even a genealogical DNA expert, but I know enough to question this interpretation of the DNA data. Rather than disproving the possibility of French ancestry, the presence of R1b1b2 appears to prove a very strong possibility of French ancestry.
From what I understand, R1b1b2 is not even called that any more, but is now redefined as R1b1a2. According to Wikipedia, “The frequency is about 71% in Scotland, 70% in Spain, and 60% in France.”
