Many years ago I tried to use DNAGedCom and it blew up because I had so many Jewish matches (all 4 of my grandparents were Jewish). So try it but be aware that if there are a lot of matches it may crash your system. Unfortunately we Jews have fewer records, and shorter surname history - and more matches than the non-Jews.
At that time, I sent a message to the administrators requesting that they let me know when their site would work for Ashkenazi Jews. I have never heard back from them.
