My husband's great-grandfather was Okey Charles Auvil, Sr. He married Rosie Elanora Hepding. Rosie's parents were Ferdinand Hepding and Emma Otillia Rhine. And, Ferdinand's parents were Alphonse Hepding and Mary Yerker. While I cannot be 100% sure, I think that this family had their roots in Germany. Do these names sound familiar to anyone?
