I am attempting to get a lead on a Berta (or Bertha) Zimmerman (or Zimmermann) who was born on October 19, 1919, and emigrated to this country on January 19, 1952. (She flew here from Munich, Germany.) I do not know in what city or state she settled, or whether she ever married (in which case her name would no longer be Zimmerman). I would appreciate information from anyone who may have leads. Thank you.
