R1b study for Black and Blake families

The R1b groupings in both Blake and Black studies are numerous and will take more time to analyze.

The Group that is labeled H Irish Ancestry in the Blake yDNA study (said to include Blakes who descend from Sir Thomas Blake b c 1183) is very similar to the group in the Black study (which includes a Blake member) bearing label Lineage V. They are related in a genealogical time frame.

The group that is labeled I Irish Ancestry (Supplementary) in the Blake yDNA study does not have any similarities in the Black study that would be related within a genealogical time frame and probably longer.

The group that is labeled F2 English East Anglia (Suffolk) in the Blake yDNA study does not have any similarities in the Black study that would be related within a genealogical time frame and probably longer.

 The group that is labeled E1 English Ancestry (4) in the Blake yDNA study does have one interesting match but it is only 30/37 so not considered significant for genealogical purposes especially as the surnames do not match.

With K German Ancestry the members have a slight match with this same Blake yDNA grouping but again not within a genealogical framework.


The possibilities for D English Ancestry (3) in the Blake yDNA are three in number but 30/37 so not a match within a genealogical framework with the Black grouping.

The last group is G Irish Ancestry (Galway-Towerhill, Kiltolla) in the Blake yDNA and comparing it with the Black yDNA study. There is one entry that is 31/37 and his surname is Rankin. I have discarded this as a non match.

Just one group appears to match one of the Black groups and that is Lineage V in the Black study and H Irish Ancestry (possible descendants of Sir Thomas Blake) in the Blake yDNA study. Sir Thomas Blake was said to be born circa 1183 and the son of Richard Caddell alias Blake. I have not done very much on the Irish Blake family so simply present this chart as it was prepared by Barrie Blake in terms of the Irish Research. I do hope to revise all the headings for the Blake yDNA study as time passes.
