I am the grandaughter of a Ronald McAllister, born in Scotland in the late 1800's, I am not sure when. His mother was Mary McAllister, her family originated in Ireland. They moved to Greenwich CT in the 50's, where Ronald had 6 children, 3 boys, 3 girls. I know he had brothers, 2 of whom were twins. He married a Bridget Mary Malloy, from Dunbarton Scotland. I have heard of a Sam McAllister in family conversation, but they are all dead now.
