Listed as living in Fitzroy,ON at the time of their marriage.
Mary Jane, her husband George, and two kids (Selina, age 3, and Gilbert, age 2, are living in Pakenham township as of the 1881 census.
The 1901 census for Almonte shows Mary Jane with her two children. I assume George was away at the time of the census, as Mary Jane is listed as married, not widowed. Her bith date comes from this census, although it shows her birth year as 1851.
