About us
There are Ashkenazi families in Eastern, Western, Northern and Central Europe who have Spanish or Portuguese surnames, an oral history of having Sephardic ancestors, or some other indicator of Sephardic heritage such as a particular custom or being a carrier of a genetic disease found mostly in the Mediterranean. Often their Sephardic ancestry has not been verifiable through archival records. We would like to find out if DNA analysis provides support of a Sephardic ancestry among some Ashkenazi Jews.
There is some historic research that documents the presence of Sephardic Jews in Eastern Europe. A YIVO summary article of this research can be found at:
http://www.yivoencyclopedia.org/article.aspx/Sephardim
In the table of Y-results, sub-categories are labeled "unconfirmed," "possible," "likely" and "confirmed" Sephardic ancestry, as well as "converso" and "possible converso." Please note that use of the term "confirmed" does NOT imply that we have found archival records to support the DNA-based conclusion. For the purposes of this project, "confirmation" means that there is a high probability that the Y-DNA match between the Ashkenazi and Sephardi or converso descendant traces back to a common ancestor who lived in Iberia during the 14th-16th centuries. It does NOT imply that the the ancestral line originated in the Near East, nor does it imply that the common ancestors necessarily lived for many generations in Iberia.
