I saw this mention of Joseph Napolean Crevasse and also believe him to be my great, great Grandfather. My grandmother Mary Emerson Luther Laird just passed away at 105 yrs - and I am doing some research on our family tree. Her mother's side of the family tree only goes back to Joseph N, his daughter Mary married William Finlayson and they had a daughter, Mattie, who was my grandmother's mother. I am interested in any information you might have about Joseph Napolean or his daughter, Mary. I know it has been quite a while since you posted on this subject but I am starting from scratch.
