The 1910 Federal census for Toledo, Ohio documents Edward R. Betz and wife Lena M. Betz residing at 2244 Trent Street, with children Edwin M. aged 8, Anna Marie aged 5, and Francis Gerard aged 2 years. Also living with the Betz’s at that time were Lena’s mother Francis Schneider aged 63, and her brother Robert W. Schneider aged 25 years.
Note that I have written my grandfather’s name as it is spelled in the census schedule: Edwin M. My father (his son) and the rest of our family always knew him as Edward. His military documents all say Edward, but in many cases in old family photos and documents he is called Edwin. I can only assume the two names were considered interchangeable.
