Great resources! I'm wondering how our group of Glasgow cousins can best join in. Our David Glasgow has taken the Y-111 test and is included on the Glasgow project on FTDNA. I'd be happy to add my DNA and GEDMATCH number (A405422) here. What should we be doing to help further research?

Yeah make this page your own and add your stuff :)

I dug a bit into the YDNA results but seems we're still a few tests away from interesting results.
