Hi Ronan
Margaret McManus was my x3 great grandmother and I have very little on her, but what I have I am happy to share. She married my x3 gt grandfather John Kimmins (the family name is actually Cummings!) in Ballyclog Church of Ireland church 21 Oct 1858. The family is all Catholic so have no idea why they married there. On the marriage certificate her father is given as John McManus, labourer and the witnesses were John Donnelly and William McManus. in the 1901 census John and Margaret Cummings were living in house 15 North Street Stewartstown, John was 76 and Margaret 73, giving a birth date of around 1828 for Margaret, birthplace is just given as Tyrone. That is all I have! Does this tie in with your Margaret Mc Manus? Best wishes, Mary
