Maybe double check the date of death of Glenn as I have no date of death, but my dad was the third of ten and he was born in 1921. There is an infant who died in childbirth on 8/1/1923 as well as my grandmother Laura Butterworth. You date has an almost perfect match with the stillborn child. I would also love to have a copy of that photo of Glenn.
I have: Grover 4/10/17-1/10/79; Lloyd 3/16/1919-6/9/84; John Robert 4/3/21-6/15/83 (Arlington National Cemetery); Stillborn infant 8/1/23-8/2/23; then on with Glen, Gene, Eelyn, Christine, Maurine, and Shirley.
