I have a gg grandfather named John Mc Coy Key who lived in Gregg Co. Texas and is buried in the Peatown Cemetary. It is my understanding he was a doctor. According to others in my family he had 5 wives and I don't know how many children. I was descended through his first wife, Matilda Armstrong. They had only one child, a daughter, Molla Key. She married Duffie Watson Gambrell.
