I'm searching for descendents of the Duplessis family to help with my family tree. Harry and Lillian Duplessis moved to Detroit from the Philadelphia area. Harry's parents were Harry and Elizabeth Duplessis. Harry had a brother, Joseph, who lived in Detroit also (I believe) and two sisters that I know of, Marie and Pauline. All of these people were born in the late 1800's. Any info will help! Thanks! Sherrie
