We too in the large R1a Clan Donald BigY project have found people with much larger than expected numbers of SNPs under YP274 (which happened about AD 1100). HOWEVER, we have enough that the distribution is, within reasonable error, the expected Poisson one.

The three surnames were Group 20 in the Walker Project and Christensen and Van Horne in the Van Horne Project. Earlier this year, a member of the Walker Group 20 did advanced yDNA testing in which the SNP Y10633 T+ was identified as the terminal SNP. Subsequently a Christensen and a Van Horne have been tested, they are both positive for the SNP. The Walker family lived in Britain probably for several hundred years before immigrating to North America. The Christensen immigrant ancestor arrived in the US in 1905 from Denmark. The Van Horne immigrant ancestor arrived in North America in 1663 from Denmark. I have not corresponded with Ken Nordtvedt, it is my understanding he places the original male ancestor of these three families as living in Norway about 2200 years ago. This also confirms and extends the estimates from the TMRCA Challenge. It was noted in the Challenge report that a node of three individuals in the Van Horne family had a higher than expected rate of mutation. It was suggested these men were not members of the Van Horne family, and that the conventional research was incorrect. The member of the Van Horne family who did the SNP test was from this node. In fact, he was the family member with the most mutations. Those of you who have high mutation nodes in your families should not discount these men, without doing additional testing to confirm or disprove the relationship. Now, can anyone tell me how we get this yDNA terminal SNP documented in the yDNA Phylogenetic Tree.

Doug, When is the closest to now terminal SNP that is found in the Donald clan? Are breaking into the genealogical time frame?
