?Larry Brett (Wendy Morse's uncle) and I are currently assigned to haplogroup R-F110.? Most Y-DNA SNPs which are used to define haplogroups have occurred only once in the history of mankind and so can be used to define branches in the Y-DNA family tree without any risk of duplication.? Unfortunately, F110 is not such a SNP: it is a recurrent SNP which has occurred more than once and in more than one branch of the Y-DNA tree.? Until recently other occurrences were not being used for naming haplogroups but that is no longer the case - I have found there is another R-F110 in a different part of the Y-DNA tree (DF21>DSF5 .... but like S16264 also derived from L21+, DF13+).? So I have sent a note to FTDNA pointing this out and suggesting our R-F110 be renamed R-FGC36619 as FGC36619 is unique to Larry's and my branch of the Y-DNA tree.? Hopefully the change will happen within a week or two.
