Hi Eva, There is an Ontario Death registration for a Michael Donnelly, who died August 13, 1906, age 80, in Peel in 'Division of Toronto'. He was a farmer, born in Ireland, married, Roman Catholic. If the 'married' is correct then when Mary died at a later date the death registration might be very informative and contain her parent's names. I could not see a death for her in Peel County but perhaps she went to live with a child. Hope this helps. Gay
