Hi, Michelle. I have not heard of a connection with a LAZAR from Hungary. However, Slovenija was part of the Austro-Hungarian Empire at that time, so it's very likely they were not really "Hungarian"? Do you have any clarifying information about why they may have said they were Hungarian? They may have done so since they were emigrating FROM Hungary. Do you know the cities they emigrated FROM in Europe.....or the cities of their birth? Do you have any place names at all (towns mentioned in family stories, etc.)? If so, it might help place the actual ethnic region of their origin. Let me know! Mary
