Thank you very much for your reply. I'm not sure that my uncle Nyusha was connected with your family. I do know that he emigrated to America in about 1923. I found a document in 1923 emigration to the Nachum Krainovich. The document stated that Nachum came to his grandfather, whose name was Mr Jacob Broida. Until 1915, my uncle Nyusha lived in Warsaw with his father Yefim, Misha stepbrother and stepmother Sarah. His own mother, to my knowledge, has died, maybe her name was also Sarah. During the war, the family was evacuated to Russia. Nyusha attended secondary school in Moscow. In 1923 he left Russia and came to America. This is all we know about him.
