I can't believe there are others looking for Egorov. My grandfather was Vasili Vasilievich Egorov. (I have several documents, all with different spellings) He was a pharmacist as well as an officer in the Russian Army, on a dipolomatic mission to Contantinople when we emigrated to the US. His father was Vasili Vasilievich Egorov. He was a physician as well as a professor. His mother was Alexandra Sidrovna Egorovna. His two sisters were Zenaida (Zoya) Vasilievna?? Egorovna? and Vera Vasilievna Egorovna? (not sure of spellings. One was a dentist, the other a physisist. They lived in Simbrisk (Now Ulyanovski). I have an address of the home they lived in. The family lost touch in the early 1940's.
Any connections, please contact me!!! I'm trying to fill the branches of my family tree as well!!!
