The years long stall in my finding records is frustrating, and at this point, the search for Mußbach above, is not relevant to my search. It must have made sense to me at the time. My German family names are very common ones. That's a problem. My paternal gf is an unnamed Ashkenazi Jew. My gm immigrated to CT in US, and my father bore her surname until he was adopted through her marriage in CT. She was b. in Karlsruhe, my father in Frankfurt am Main. So what does one do after years of looking?
