The goal of the Jewish R1b project is to serve as a gateway for anyone with paternal line Jewish ancestry whose predicted or confirmed haplogroup is R-M343 or any downstream branch. Members will be sorted and grouped with their closest matches in order to identify Jewish subclades (branches) of the Y-DNA phylogenetic tree. This will help all our members to understand their relationship to the others in their subclade with whom they share a common paternal line ancestor. To improve the knowledge of members and the overall understanding of Jewish history and migration, the Volunteer Administrators will: 1. help identify members' presumed haplogroup and advise them on additional (NGS) testing (SNP Pack or Big Y) 2. add members to appropriate specific subclade projects for deeper analysis and understanding 3. facilitate the creation of new subclade projects by interested genetic genealogists. Although about 50% of all Western European males belong to Haplogroup R1b (R-M343), it is found in only about 10% of the Jewish population. Analysis of the Project’s Next Generation Sequencing (NGS) data is critical to identifying Jewish lineages (branches) as distinct from this very large segment of the current European population.
