Sophie Martel, d/o Victor Martel and Rosalie Cote. She married Mitchel Cabana in Mansonville, P.Q., Canada.
There are Catholic church parish registers that have information on births/baptisms/deaths. The one that has the marriage information for Sophie Martel and Mitchel Cabana is St. Cajetan's church.
It is a bit confusing, there were two Victor Martel's:
One married Rosalie Cote, and after Rosalie's death, married again to Mary/Marie Houlihan.
The other Victor Martel is the son of Victor Martel and Rosalie Cote.
Sophie is listed in her brother's obit (Victor Martel), in the July 1, 1968, edition of The Lowell Sun (Lowell, MA). He died in Ayer, MA. The obit says he is survived by a sister, Mrs. Sophie Cabana--but no other information on her is given.
Have you checked the online family trees. There is a lot of information on the Martel family. This one is fairly accurate:
