My great grandfather's sister (Annie/Esther/Rose Rosenblum b. ca. 1877) married Isaac Friedman. I do not know where my great grandfather and his sister came from - all the census, ship log, etc. docs I have found, indicate Russian, Austrian, or Russia Poland. But Isaac's 1930 typewritten Petition for Citizenship says that Isaac's wife is from Tomergut, Russia. I can't find any place that could possibly be Tomergut - any suggestions? (I did find a Tonnerhütte in the Austrian alps but it doesn't appear to have ever had a Jewish community.
