I am searching for information on Johann Rzehak and Anna Dam. They are my grandparents from my mothers side. Elisabeth Mathilda Rzehak (Vogt) died in 1990. Cannot ask her the questions so if any one knows or think they might know some amswers please let me know. My mother had a girl before she married my father in 1950. Her name is Helga Maria. I think she was born around 1940 to 1945. When she was 2 she was removed from my mother and placed in a catholic mission and then adopted out. she suppose to be living in the franfurt to berlin area. I only found out I had a sister after my mother died. So if any one can help please.
