Untangling a Tumbleweed Branch of the Y-DNA Tree (John Brazil)

What will you be talking about?  The genetic relationships between men who possess the Y chromosome R-A151 haplotype, the geographical distributions associated with this and its various sub-branches and historical events that may have contributed to this. What is the relevance of this to Ireland & Irish genealogy? The R-A151 haplotype is itself a sub-branch of the R1b-CTSS4466 haplotype, a haplotype that is closely associated with Munster in the south of Ireland. I'll discuss the genetic relationships between men possessing these haplotypes, their surnames and the locations reported for their Most Distant Known Ancestors and trying to identify historical events before and after the adoption of hereditary surnames that might have contributed to the social turbulence and geographical dislocation associated with this distribution. To what surnames is this topic relevant? Brazil (Wexford in Ireland), O’Connell (Kerry, Limerick and Clare in Ireland), MacAulay (of Lewis and Harris in Scotland), Thrasher and Davidson (US), Hill (US but also England and Sweden), Shinnick (Cork in Ireland) and Fox (in Tipperary in Ireland). And various surnames of Welsh and Scandinavian origin. This lecture was presented at Genetic Genealogy Ireland 2018 in Dublin.
