Hi Peggy,
Have you ruled out the Mary Bone born in Aberdeen on the Family Search IGI site? I looked for the death of Mary on the
Manitoba Vital Statistics site, and it has her age as 72, which would give 1831 as an approximate year of birth. The following is the only Mary Bone born in Aberdeen between the years 1825 and 1835, and she just happens to have been born in September:
IGI Extracted Entry: Mary Bone, birth 26 Sept 1831, Tyrie, Aberdeen
Father Alexander Bone, Mother Ann Murison.
There are seven children entered for this couple, starting in 1830 up until 1845, all in Tyrie. (Anne, Alexander, Isabella, Mary, Jean, Catherine, and William.)
Unfortunately, these dates do not fit the dates you have from the 1901 Census, but we all know what tangled webs those can sometime weave!
