This is a Y-DNA Haplogroup Project for SNP G-Z6748, which is downstream from G-M201 >> L89 >> P15 >> L497. All participants who are Z6748+ are welcome to join, including any of its downstream variants. Many of the subclades of G-Z6748 appear to be 'Welsh' haplogroups, athough subclades are also found in neighboring parts of England, Ireland, and northern continental coastal areas of the Netherlands, Belgium, and Northern France.
