Would you be interested in signing up for the Jewish Roots Project? That is a place where all of us who are discussing the problems of finding our lost or invisible Jewish Ancestors are collaborating inside of WikiTree. There's also a Jewish cemeteries person Star Kline who might be able to assist. If all this fits please sign up for Jewish Roots Project. (HOW to get started today on JEWISH ROOTS PROJECT? in "G2G Help": under Requests for Project Volunteers for posting questions like this one.
