I'm researching the McGuinness' from Cavan also.My GGrandmother was Mary McGuinness B 1841 Cavan. Father Peter? from Drummanbane Townland. Married James O'Reilly from Lisnafana. Died 1911 in Drummanbane on the road N3. Sons: Con O'Reilly Drumfominia, Bernard NY, Hugh, sisters: Mary NY, Annie NY, Maggie. The McGuinness' came from Fermanagh near the border of Monahagn originally. They were well to do before they lost their land. I heard there was a Bishop in the family. I'd like to know where Mary was buried and more about the family.
