Did Joe Yoss have a relative named Ivan Yoss? Perhaps a nephew?
I have a woman named Olive Glenn (my dad's first cousin) who married a Harry Yoss, and they had son named Ivan, b.Scranton, IA c.1905, d.Cedar Rapids, IA c.1982. I have Ivan's obit with exact dates, but not in front of me right now. Olive's parents were Caroline Youmans (1855-1924) and Allen Glenn (1849-1931).
