Lasairfina’s Lough Key Gift
Archived: 25 October 2026
In 1239, Ireland’s fragmented politics combined warfare, lordship and religious patronage. Domnall Mac Lochlainn defeated rival forces at Carnteel, regaining Tír Eógain after Anglo-Norman intervention. Maurice FitzGerald’s forces raided around Sligo, probing Ó Domnaill territory without securing lasting conquest. In Breifne, Fergal Ó Raigillig’s killing illustrated regional and dynastic conflict, though its date is disputed. Lasairfina, daughter of Cathal Crobderg Ó Conchobair and wife of Ó Domnaill, granted land at Ros Birn to Trinity Abbey on Lough Key. Cashel confirmed Dominican Dáuíd son of Cellach as archbishop. Annalistic discrepancies caution against certainty, while revealing intertwined power, land, kinship, and church.
