Roseanne,
I have quite a bit of info on the Payment family genealogy and I don't have a record of an Angélique Payment with Antoine Théorêt. However, I do have Marie-Angélique Payment, daughter of Louis-Antoine Payment dit Larivière & Marie-Angélique Presseau dit Gauthier, married to Joseph Théorêt, son of Joseph and Marie Josephe Massy, on 22 Jun 1812 in Sainte-Geneviève de Pierrefonds, PQ. This couple had a son named Antoine who married Eulalie Poudret dit Lavigne, daughter of Jacques and Marie Louise Cousineau, on 25 Jul 1842 in Sainte-Geneviève de Pierrefonds.
I hope this information is of some help.
Louise
