About us

This project is for men who have done Y-DNA testing and their terminal haplogroup designation by Family Tree DNA will be either E-Y6923 or one of its downstream branches, E-L791, or it will be predicted E-L117 or E-M34 with Y matches who are E-Y6923 and/or E-L791. The Y6923 SNP is found downstream of E-L791, and likely occurred about 1,650 years ago. Its main Ashkenazi branch, defined at FTDNA by E-Y6940, dates to about 1,250 years ago, and seems to have been one of the major founding branches of the early Ashkenazi community. Other branches, which have been found in North African Jews and Latin Americans of likely Sephardic descent, include E-Y102667 and one yet-unnamed branch. Because of this project's narrow focus, the only way to contribute to this project right now is to have DNA results that suggest that you have the Y6923 SNP marker on your Y-chromosome. While you do not need to have tested or confirmed this marker to join this project, the project administrators will be able to predict from your existing Y-DNA results whether or not you likely have this marker and will be able to confirm whether you belong in the group from your Y-DNA results once you join. If we determine that you aren't likely to be positive for the Y6923 we'll send you a note with an explanation as to why.
