I'm a decendent of Joseph Phenix's brother, Francois Amable Dauphine (same name as his father) b. 27 Jun 1731 d. 17 Dec 1786. Don't know if that's what your looking for. But I did obtain a lot of info from ancestry.com. The Common family member for us would be Joseph Phenix's father Francois, who is my Great-great-great-great-great-great grandfather.
