Hi.I'm not related to this family.Here is their marriage from Quebec Vital and Church Records (Drouin Collection), 1621-1967:
Eugene Hervieux (Medard & Marie Erline Bessette) m. 16 Feb 1884 Montréal(St-Jacques, cathédrale de Montréal), Quebec Elizabeth Flynn (Thomas (deceased) & Mary McGuire)
The Hervieux family was listed as parishioners of St-Joseph of North Adams, diocese of Springfield, Mass, and the Flynns were parishioners of St-Michael of Springfield, Mass.
I wonder if this is Eugene & Elizabeth in 1900, even though the wife's name is listed as Margaret:
1900 United States Federal Census about Eugene Harvey Name: Eugene Harvey [Eugene Karver] Home in 1900: Worcester Ward 3, Worcester, Massachusetts [Worcester, Worcester, Massachusetts] Age: 37 Birth Date: Jun 1863 Birthplace: Canada Fr [Canada French] Race: White Gender: Male Immigration Year: 1867 Relationship to head-of-house: Head Father's Birthplace: Canada Fr Mother's Birthplace: Canada Fr Spouse's Name: Margaret Harvey Marriage year: 1883 Marital Status: Married Years married: 17 Household Members: Name Age Eugene Harvey 37b.

Dec 1897 Mass Mildred Harvey 10/12b. Jul 1899 Mass
I found a birth record for their son Joseph:
Joseph Stanislas Eugene Hervieux, b. 7 Sep 1885 Montréal (Basilique Notre-Dame), Quebec, son of Eugene & Elizabeth Flynn.-godparents- Stanislas Pariseau & Clara Hervieux, his wife and also uncle and aunt of the baby.
I know there is plenty to find on the Hervieux line, but I'm not having much luck finding Elizabeth prior to her marriage.
Let me know if you need info on the Hervieuxs. Definitely that family line can be traced.I can tell you right now that in 1880 they were living in Hampden, Mass.Annie
