François Soucy: son of Germain Soucy married to Marie Anne St-Pierre on July 11, 1791 at St-Roch-des-Aulnaies, QC.
Céleste Fournier: daughter of Pierre Basile Fournier married to Josephte Fortin on June 18, 1787 at St-Jean-Port-Joli, QC
The son of François and Céleste, François Soucy Jr, married Rosalie Demers (Gabriel and Josephte Lemay) on January 23, 1844 at Lotbinière, QC. The couple lived in Lotbinière many years before moving to the USA in the 1860s. François Soucy Jr died in the Lewiston, Maine area (maybe Turner) in 1889 while Rosalie passed away in Lewiston ten years later, in 1899.
Hope this helps.
