Via Family DNA I have tracked my Y-chromosome down to L21, and further down to Z255 with a final haplotype of R-CTS12583. I think this is also known as S3802. I have definitely tested negative for L159. I can find no information at all about Z255 apart from it originating 1500 years ago. I assume it originated in Ireland but really have no idea.

Any information greatly appreciated. My email is [email protected]
