I am looking for the parents of Alvina Therrien, married to Pierre Oscar Montpellier. She was born in 1864 and died in 1947. their son Wilfrid Montpellier is my grandfather

The one I can find was married to Pierre Villeneuve.  They got married at St-Jacques, Montréal, on november 27th 1882.

Malvina was minor.  She was born on September 24th 1864, baptized the day after at St-Jérôme.  So, her parents are Jean Therrien and Hortense Piché.  The death record says she died on august 8th 1947 at Montréal.

 I found the good one.  Oscar Montpellier married Alvina Therrien at St-Luc-l'Évangéliste of Curran, Ontario,  on July 25 th 1886.

Alvina parents are Ambroise Therrien and Elisabeth Deguire.  I think these two got married in Rigaud, Québec, in August 1856.
