Hi, Just found this info some almost two years after your question. Enclosed is the link to their marriage record from the Provincial Archives of New Brunswick.
Leo was son of Philippe Boudreau & Marie-Anne Cormier
Leonie was daughter of Camille Arsenault & Osithe Bastarache
Go to the search page on this link and you can get at least another generation back.
