I need a little more information to make an informed opinion whether we may be talking about the same person. The name is a bit unusual, which is a point in favor. Also, the birth year is within tolerable limits. According to family sources, "my" Philomene" was born 28 May 1839. There is the possibility that that is a baptismal date, however. The place was St-Antoine-de-Padoue.
Can you please provide more information on your Philomene? Have you found her in census records? What is the place of birth? What is the given name of her husband? Judging from the ages of her children, what is a likely marriage date range? Did the family stay in Canada or immigrate to the United States? When and where did she die? Do you have a formal death record with information?
I see the following in the 1881 Canada Census, who might fit. Are any of these, yours?
Antoine and Philomene
Bessette (age 43), Ste-Alexandre, Iberville, Quebec
Solyme and Philomene
Bessette (age 44), Iberville, Iberville, Quebec
Jean-Baptiste and Philomene

Merci. Kenneth W. Parent
