When all the dusty family trees books and scribbly civil records have been exhaustively mined (and I believe that time is rapidly approaching), yDNA-based rabbinical research is the way forward.

The 24 current index listings are mostly the result of prior published work by various researchers. The next step is to discover new signatures using the data-rich GENI platform.

Volunteers are needed to obtain new yDNA signatures. Please join the project by creating a free GENI account and visiting the project website:  https://www.geni.com/projects/Rabbinical-Lineages-yDNA-and-Haplogroup-Identification/58725. A focus list of about 50 high-probability research-ready lineages, many renowned, is available to volunteers at the project site. Instructional and workflow guidance provided for immediate immersion. This is highly rewarding and fascinating work, of benefit to the entire research community.

The current indexed lineages, which may also be viewed at the project site, include the following Rabbinical lines:
