My g g grandfather name was Reich and he was from Austria - Hungary. He left to Poland met his wife and decided to stay in Poland. Our name is now Rajch , I don't know why and who changed it. I think it was easier in polish language "AJ" not "EI" I know there is family in Lublin, but would love to find more about my g and g g grandfather from Austria. Where will you suggest to start looking?

Best regards, Rajch
