About us

J2 Y-haplogroup members with extra DYS 464 copies, whatever their surnames, are the focus of this study. (These are markers reported as DYS 464e, or letters beyond e.) This is a regional and deep ancestry project, rather than one based on a single surname.

ELIGIBILITY CRITERIA: If you are J2 and have an extra DYS 464 copy, or if you match at least 23/25 or 33/37 at FTDNA or on Y-search with another J2 who has an extra DYS 464 copy, you are eligible to join and help us determine the significance of the extra DYS 464 copies.
