This group consists of people who have done Y-DNA testing and match significantly on 37, 67 or 111 markers---many of whom have also done the BIGY test---and who are known to be in a subclade of J2a-L26, primarily L24 and downstream. There is a major subclade within this group (J2a-L24-FGC4992) made up of a large contingent of Jews with a cohanim tradition and if that description applies to you, I will contact you about the amazing discoveries we are making in that group. However, the project as a whole includes Arabs, Berbers, Mesopotamians, Turks, Italians, French, Spaniards, (all Europeans, actually), Southwest Asians and even more far--flung matches --all of whom are super valuable as we work towards our goal of identifying our greater clan's origins, migrations and divergences over the last 4500 years or so. We're also tracking all late-breaking news about our J2a* haplogroup so we can know our clan's likely travels over the last 10-15,000 years. If you love history and finding your place in it...and are a genetic match with any of us---or want to take the DNA test to find out...please join! NOTE RE SURNAME LIST---This is just a small sampling of the names of members of this project...our connection is via our genetic and genealogical pasts, and for most of us, the surname doesn't go back past the 18th century....so for the big picture we are piecing together, modern-day surnames aren't really that important.
