One more thing. If you are customizing your own Family Group Sheet for Jews, then there should be separate entries allowed for their secular names, Hebrew names, and Yiddish names, as well as nicknames. many Hebrew and Yiddish names are equivalent to each other, but seem quite different to those of us not raised where both are used. Not all families will give their children Hebrew and Yiddish names, but if you can take your wife's Jewish side back far enough, you may well run into ancestors of hers whose records sometimes show their secular names, sometimes their Hebrew names, and sometimes their Yiddish names, all for the same person. If you have not visited it, http://JewishGen.org has a lot of helpful information about Jewish Genealogy, and includes given names databases where you can research which names are equivalent to each other.
