Born in Killin parish, Perthshire, Scotland, daughter of John Robertson and his wife, Ann McDiarmid.
Married Hugh Ferguson in Killin in December,1831, and emigrated in the late 1830s with him and their 2 young sons to Howard township, Kent county, Ontario where they joined Mary's sister Ann Robertson and her husband, James McGregor. Mary's elderly widowed mother, Ann Robertson (nee McDiarmid) apparently made the long journey with them.
Not too long after their arrival in Canada (ca. 1840), Hugh Ferguson died. Sometime thereafter, Mary married her sister's step- son, John G. McGregor who was several years her junior, and the couple produced 5 children whom they raised together with Mary's 3 Ferguson sons.
Mary died in Howard township in 1899.
