Marie Eugenie Jarvis b.1849 d/o Eric Joseph Gervais and Delia Montjean

I have Marie Eugenie's marriage record. Marie was born June 11, 1849 in Chateaugay, New York and was married in February 1870 to Joseph Henry Guyette. Marie's parents are listed as Eric Joseph Gervais and Delia Montjean. They are probably from Quebec.

Any info on this line would be appreciated.

Thanks

Julie
