Tom, Let's see if this sorts it out for you.Drouin has Emerentienne Miville marrying Jean Dessain, s/o Jean Dessain and Magdeleine Pinet, on 11 August 1835 in St-Jean-Port-Joli, QC.Talbot shows Clementine Deschesnes marrying Jean St-Pierre, s/o Jean St-Pierre and Madeleine Pinet, on 11 August 1835 in St-Jean-Port-Joli, QC. Drouin shows her as the daughter of Juste Miville and Theotiste Chouinard while Talbot shows her as the daughter of Juste Deschesnes and Theotiste Chouinard. Talbot standardizes all Miville and Deschenes variants into Deschesnes.Drouin transcribes what is used in the marriage Actes. The St-Pierre surname is associated with Dessain and Dessain-dit-St-Pierre.I believe that these are the same two persons appearing as two other persons because of surname variations. Both surname variations are well documented.
