I'm trying to find a birth record for a David Stobbe who was born in Saratov around 1919. He had a brother, Arthur and two sisters, Else and Matilde. They ended up near Krakow, Poland at some point and David married in Germany before coming to Canada. I have no other information at this point. I have a feeling that David's parents were Mennonites, but I can't prove it.
Any information or ideas of where to look would be appreciated.
