About us

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). We will accept men who have Y67 or Y111 matches with R-L1335> men, and any patrilineal cousins of R-L1335> men. We strongly recommend the Big Y-700 test, which has significantly grown the R-L1335 haplotree into recent times.
