Hello. I've hit a dead end on my husband's family tree and would appreciate any help. His great-grandmother was Katherine Helen Colvin, born Feb. 17, 1906 in Utica, Indiana. She married George Albert Antz on Sept. 22, 1924. On the marriage record, her parents are listed as Chas Colvin and Unkn Hopper. Any help at all to her mother's identity or information about the Colvins would be greatly appreciated!
