BritainsDNA Chromo2 Y-SNP Results Spreadsheet

I received an email from Dr. Jim Wilson of BritainsDNA today which included a link to a spreadsheet with Chromo2 Y-SNP results. He has given me permission to publish it with his comments:

We have finally got round to releasing an anonymised dataset of ~2000 chromo2Y results. This is an excel sheet with ~14,200 SNP results for ~2000 random men using the chromo2 chip, so will be a goldmine for discovering further genealogical structure in European haplogroups. I think it will be of great interest to genetic genealogists and others who are interested in breaking down their haplogroups and subgroups. 

The link is:

Thanks again, Jim!


  1. RE: R1b-L371 (aka S300). A Welsh Y-SNP

    A. New World: US's FTDNA R1b-L371 (aka S300) frequency =.1% (~1 out of 1000 men tested by FTDNA)

    B. Old World: England's BRITAINSDNA R1b-L371 (aka S300) frequency =.1% (~1 out of 1000 men tested by BRITAINSDNA)

    The equality of the ~.1% frequency among A.& B. does indicate that this Y-SNP Haplogroup is relatively rare "geographically overall" in Great Britain as a whole (England, Scotland, Wales) and North America as a whole (USA, Canada)

    The ancestral homeland of R1b-L371 (aka S300) is likely in areas of NW Wales and it is associated with patronymic surnames such as Griffith, Jones, Davis, Pugh, Thomas, etc. If the POBI study (People of the British Isles) or other studies were conducted in NW Wales limiting such to the above patronymic surnames, geographic hotspots for R1b-L371 (aka S300) could easily be mapped likely showing frequencies 3 to 7 times higher than the .1% frequency. On an Autosomal DNA basis this has been done by POBI showing unique DNA signatures in North Wales vs. South Wales.

    Professor Peter Donnelly, of Oxford University, said the Welsh carry DNA which could be traced back to the last Ice Age, 10,000 years ago

  2. So why can't they associated surnames with these results? The individuals would still be anonymous, but it would be quite helpful to researchers.
