Hania, Thank you for your response and your help. My grandfather was born in Leningrad (I thought it was St. Petersburg so am not sure really which). His family fled from Leningrad to Paris in 1920. His father George was born in St. Petersburg. I am unsure of where his mother Ludmilla Teisenhausen was born, though. Her father was Gustav Teisenhausen. I feel if I can get some of information of his parents or grandparents it may help me with migration. Sasha was in the Normandie Squadron of the French Red Air Force so he spent time in France in the 1930s and 1940s. Apparently he volunteered for the Free French in Argentine in 1940. All this tells me only of his military background, which I am interested in. but I want to now if he and his second wife ever had children as she is now dead.
