I am researching Granton. In 1999 my cousin and I had access to the Sacred Heart Church, Paris, ON, records and found the marriage of Michael Granton, on November 21, 1860, to Anne Magher, d/o Thomas Magher and Judy Bergin (we may have had trouble with deciphering the writing because there is ? beside her parents' names). We found no record of any children for them at Sacred Heart Church.
We found the marriage on November 25, 1869, of Anne Granton, widow, native of Ireland,d/o Thomas Maher & Julia Berrigan (again a ?) who married John McDonald, from Scotland.
This marriage was transcribed for the Ontario Vital Statistics Project (at rootsweb.com)as:
4/58 John McDONALD, 36, widower, laborer, Scotland, Paris, s/o Donald & Sarah, married Ann GRANTON, 30, widow, Ireland, Paris, d/o Thomas & Julia MAHAR, witn: John McKINNON & Mary Jane HOVEY, both of Paris, 25 Nov 1869 at Paris (Rom Cath).
I know nothing further about them but she seems to be a sister of your Patrick.
