The informant was Fred Bennett, St. Louis, MI. William's cause of death was cerebral parylsis and he was buried 19 Mar 1923 in Paulding Cemetery.
I can't locate any death cert for Mary, whose maiden name was CUMMINGS or anything close. However, maybe she was married before and her maiden name was something else. I can't find any Mar* Cum*, born Switzerland ca 1845, in the 1860 census, any state.
