Toward the end of last week I emailed BritainsDNA and asked for some stats on S524/DF41. A couple of days ago, I heard back from Dr. Angelika Kritz of BDNA. Here are the stats she gave me, exclusive of the R1b-S388/L745 Royal Stewart lineage and the SNPs L563, S273 and S8311, which she identified as almost exclusively Scottish. Dr. Kritz said S524 (DF41) is most common in Scotland, at 3.9%, followed by Wales at 1.4%, Ireland at 1.0%, and England at 0.5%. Those are percentages of the total y-dna and not merely of the R1b or of the S145/L21.
Dr. Kritz did say, ". . . [I]t is likely that there is a Welsh cluster below S524 for which we have yet to find a defining SNP" and mentioned that three of their Welsh S524+ customers carry the surname Jones (not surprising in Wales obviously). I have two Joneses among my haplotype matches.
Of course, I think the defining SNP for that Welsh cluster is BY178 (among a number of them), which turned up in Big Y testing of myself and two other members of my cluster and in subsequent SNP testing of another cluster member.
Anyway, it would be interesting to see a map of the birthplaces of the most distant known ancestors of these R1b-DF41 BDNA customers.
