Charles and Theresa were my grandfather's parents. His name was Paul M. Steward, he passed away in March 1995. My grandmother (Paul's wife) is still alive and will be 92 this month. She lives in Stillwater, OK.
The story I was told about Charles is that he was a traveling salesman in Oklahoma who passed away on the road when my grandfather was very young 3-4 yrs old i think. He was the youngest, born in 1912-1913 or so.
My father told me he knew Theresa however, I don't remember exactly when he said she passed away - 1950's I think.
I believe I have a photo of her, not sure if I have one of him.
I've never attended however; there is usually a Steward family reunion in Gainsville (I think) Texas every summer.My brother in Dallas has attended a number of times.
