This may or may not be relevant to you: My grandmother was Martha Nussbaum Elsbach, b. July 1901, in Schmalkalden. (I'm not exactly certain where that is.) Her parents were Seelig(Sally) Nussbaum and Therese Meyer(d. 1940). I don't know their dates of birth, but they died here in the U.S. Unfortunately, I don't know their parents names, either. I wish you success.
