I don't know anything about the Ganzer side. I am researching the Peters name. Minnie Ganzer was Minnie Peters. But that is all I know. In 1930 census she was living in Vernon, Wilbarger co. Texas with two daughters and a son. She is listed as a widow and did laundry. I hope your Minnie is the same one. As far as Paul Ganzer is concerned, I'm sorry I don't have any information on him. If you know Minnie Ganzer's maiden name that might be the connection. Thanks for the contact. Happy hunting!
