Your grandfather Harry was brother to Elizabeth Ganzer, my grandmother. I just wrote a long note to Heiko about Bert Ganzer. I think you will find the information posted of use.
Lois Smith (nee Brockman) is Elise's daughter. She passed in 2005 but was working on the Ganzer family history. As I told Heiko, mom put together a lot of information. Uncle Harry and Aunt Linda ( nee Laechel) had 4 children: James Harry Ganzer, Ralph Bertram Ganzer, Floyd Franklin Ganzer and Marilyn Lois Ganzer.
