Find a grave has a memorial (#31491123) for a Harvey L Snyder. Born 1904 (matching 1940 census above) and married to a Hazel E. Snyder with an inscription on it that says Married July 21, 1927. He died in 1982.
He is buried in Spencerville Cemetery in Allen County, OH, USA.
It's possible you could request a death certificate from Ohio for Harvey, and you may learn from the "informant" more information: and it may have been his daughter Peggy June. Or Peggy (and a married name).
I find it challenging to find out information about women (who are likely married) and in the modern timeframe - as there are definite privacy issues/laws/restrictions.
