This family is listed in the 1881 Census in Simcoe North with 11 children. They are also in the 1852 Kenyon Census as Alexander MacDonald and Catherine Munroe but have two children with them. They are Peter 15 years and born Ontario and Elizabeth 16 born Scotland (maybe sister of Alexander) They are all Church of Scotland. The 1881 census show them as Presbyterians. All my church records are Catholic so you will need to find the marriage info on Alex and Catherine.
