A Y-Chromosome DNA study of the early Scots, Irish and UK Atlantic Isles and Scandinavian inhabitants with an uncommon genetic signature. (Participants are tested positive or predicted to be positive for SNP R1b-L1335 and its downstream SNPs). PLEASE do not try and join unless you have already been proven to be R-L1335+ If you are merely wondering, please either test that SNP via FTDNA or more economically, test the R-L21 SNP pack. (The best test you can buy is the Big Y, because when coupled with Y111, the two outcomes compliment one another - that is, they work hand-in-hand. If you have NOT tested and been found positive for R-L1335, then please provide a full explanation as to why you consider you should join this project. Anything less will mean you will be denied.
