According to baptism records, Joseph was the son of Michel Mercure and Marie Angélique Potvin of Saint-Basile, Madawaska, New Brunswick, which is now at the northern tip of Maine, across the river from Edmundston, New Brunswick. There’s a rival claim that his parents were Louis Mercure (1753-1817) and Marie Madeleine Thibodeaux (1748-1795), who married on 1 Dec 1772 in Acadia.
Louisette was probably also from New Brunswick. Her parents were Charles Létourneau and Marie-Martha Bernard.
Joseph and Louisette married on 30 Aug 1825 in Saint-Basile. Their first child, Émilie, was born there. They were reportedly living in Richibucto, New Brunswick out on the coast by 1829.
I’m having a hard time believing that almost 14 years passed between the births of the penultimate and final children.
Émilie has her own entry in the family tree.
