Who is related? We find Glantz immigrants to Pennsylvania, Glontz cousins today in Pennsylvania, Clontz members in the Carolinas and Texas, Klontz cousins in Ohio, Illinois, and Washington. Members of this family use many spelling variations of the surname. Brothers even spelled their name differently, so spelling alone does provide answers. Our study augments our paper research to determine which family groups in America share a common ancestor, even perhaps in Germany.
