Hi Igor, I came across your page searching for information about my grandparents Dr Vladimir Chistov and Alexandra Chistov. My mother was their daughter and Oleg was my uncle. I was so surprised to find out somethings I didn’t know about them. For instance, we only ever Alexandra’s maiden name was Flerov and never heard the name Junicki, so am a bit confused about that. However,I am very pleased to learn more about them because of your blog. Thank you very much.
