Francis Sellman Carroll was my grandfather. I don't have a lot of specifics with me at the moment. He died in Washington, D.C. in the early 1950s. His wife, my father's mother, died in a car accident in the early 1930s.My father was their only son, Norman Sellman Carroll, who died near Washington D.C. in 1978. Contact me and I'll be happy to share more information.
