I don't know if there's a connection, but my Tollison's are also from OK and CA. My father, Vernon Monroe Tollison was born in Tulsa, OK, and later moved with the family to Visalia, CA. His father (my Grandfather), Monroe Tollison lived in Vasalia when he died, but also lived back in the southern states for many years before that. He was first married to a woman named Virgie and then to a woman named Minnie or something like that. My father eventually moved to Oregon where he died 3 years ago. I don't know if it's a match, but good luck to you.
