Gladys H Ammon was a cousin of my mom's, Charlotte Agnus Smith Ebel. Her father was Percy Arden Smith.

Percy was born March 7, 1891, Died July 1972. Was married to Agnus Elizabeth Seltzer.

Gladys was born November 23, 1911 Died March 22, 1990.
My grandfather had 8 brothers and sisters. I can't remember them all at this moment. Leroy, Carrie Smith Haaf,, Milda Smith Cocran, John, I believe on was Arthur. I think Gladys might have been one of his sisters, but I think more than likely she is the daughter of one of his brothers. If this helps I'm glad to be of service.
