Agnes' first husband was Michael Quinn. I am guessing that Michael was ill because he was living with his father's family in 1911 (Census of Ireland,) while Agnes and children were living in the home of Cormack Quinn. The lived in the same town.
In any case, Michael Quinn died (of Bright's disease, for 2 months, as witnessed by his mother) on September 23, 1912.
Agnes married John Kane on October 18, 1913 at the RC Chapel at Frosses, Mountcharles, Inver, Donegal.
