In my Denault/Deneault collection of marriages, I have a Pierre Denault who married TWO women named Domitilde:
Pierre Denault, son of Michel Denault and Suzanne Tremblay, married 1st Domitilde Guay, d/o Prisque Guay and Marguerite Gamache, on 12 July 1853 at St-Valentin, St-Jean, Quebec (source: Mariages du Comte de St-Jean (1828-1950),(B. Pontbriand, Quebec, 1974, Pub. #97))
He married 2nd, Domitilde MONDAT (I didn't note her parents) on 7 January 1860 at St-Remi-de-Lasalle, St-Remi, Napierville (source: Mariages du Comte de Napierville,(B. Pontbriand, Quebec; publication #95; 1973).
Thought it was close enough to mention. Shari Strahan
