I am searching for a Berta (or Bertha) Zimmerman (or Zimmermann) who was born either in Germany, the former Austria-Hungary or the former Czechoslovakia, and who emigrated to this country (I don't know to what city or state) from Munich, Germany in 1952, at the age of 33 (she was born on 10-19-19). There is, of course, a good chance that she married, so that her name would not now be Zimmerman - if she is still alive. Any leads or suggestions?
