Maybe someone can either help me or give me some ideas about locating an ancestor's obit, or date of death. She appears at age 73 living with her daughter, Louisa Prue, in the 1880 Kankakee, Kankakee County, Illinois.
Her actual name was Marie Justine Nicole born c1807 Canada, she married Charles Proulx, used surname Prue in USA.
She obviously liked name of Christine as she used that in many USA censuses. I've checked FAG and many descendants are listed in a Kankakee, Kankakee County, Illinois cemetery but she is not. Husband Charles Louis Prue died c1860 or after 1860, resided Newton County, Indiana. TIA
