Sorry can't help either, althoughI did went to school with a Philip Kersaint related son of a French women and one of the Kersaint brothers, I did lost contact with him. By the way Where are you located with that surname and an interest in Haiti. My great grandfather's name was Hermann Stephenson, British citizen married Angele Riboule in 1st marriage then Jeanine Borday. Hermann was son of William Badwell Stephenson and Eudora Stines. I will look in the family tree to see if their is any Kersaint listed. If you have some info on your own let me know.
