I am also a descendant through Dominique Payan and Marie-Louise Laporte. His son Jacques Payan St Ores, Jakob St. Ores who fought in the American Revolution. Pension records for Jacques and Pierre are available at the National Archives records.
Jacques married Abigail Potter in Stillwater, NY. Still looking for additional proof of his father being Dominique.
30 years of research and tons of gathered information to share.
