Thank you very much for this information. Yes, I think what you have said is accurate; however, my father did say his mistress was Czech and at one point told my mother he was not coming home, so the relationship was more than a "one-night stand." I don't know if there were many Czechs in Eastern Germany during those days after the occupation, but it's worth putting out a query on the Wiesbaden board. Thank you for very much your help. If you think of anything else, please drop me a note.
