Hi. I'm not related to this family. Here is their marriage from the Quebec, Vital and Church Records (Drouin Collection), 1621-1967 :
Lucien Gagne (Jean-Baptiste Gagne & Aurelie Gamache) m. 11 Aug 1879Roxton Falls (St-Jean-Baptiste), Shefford Co. Eveline Cote of St-Joachim-du-Maple-Ridge (Louis Cote & Eugenie Campbell of St-Joachim-du-Maple-Ridge)
Here is the next marriage in the Gagne line:
Jean-Baptiste Gagne (Joseph Gagne & Genevieve ?Laroche) m. 2 Feb 1858Henryville (St-George-de-Noyan), Iberville Aurelie Gamache (Antoine Gamache & Marie Anne Jacque)
And in the Cote line:
Louis Cote (Louis Cote & Zoe ?Lupon) m. 25 Jan 1859 Henryville (St-George-de-Noyan), Iberville Eugenie Campbell (Benonie Campbell & Marie Landry)
This is probably Eveline in 1871:
