Need beginner advice - Hirsch family from Roth
Have been doing the US-side of the tree until now, time to move to the German generations and I need some advice from someone experienced. Here is what I know: I have many (all?) of the sibilings who emigrated to the US in the period 1880-1920. I have the hometown they emigrated from. I have the parent's names (who did not emigrate). Wanting to find info about that generation that did not emigrate (and back from there). The family is Jewish and from "Roth". When I check the Meyers Gazetteer is see several possible Roths, but don't know enough to know for sure which is correct. I suspect it is a Roth near Nuremburg (based on some other sibling marriage records). I do have a photo of one street with the family home in the target Roth, if that helps. Wondering what you would suggest to: 1) determine the correct Roth, 2) start searching for records from there. (Have already checked as many name-based searches as I can think of on FamilySearch, Ancestry, and JewishGen).
