Trench, of Gerbally, Galway. MP for Galway 1761. Through his wife his family acquired al;l the Power estates in the baronies of Leitrim, Dunkellin and Loughrea as well as the Keating estates in Kilkenny, Carlow and Dublin, which she'd inherited from her mother. The Power alliance was of great consequence to the Trench family, for in addition to the vast increase in wealth, it brought them ancient titles to Norman and Irish nobility. Her father, David Power of Coorheen was a descendant of the Norman Sir Geoffrey Le Poer of Dunisle in the County Cork and their Cromwellian grant in County Galway included some of the territory of the original grant in Kenmoy in the barony of Leitrim to Eustace Le Poer the Munster baron in1301. The great-great-grandmother of Francis Power was the daughter of Cormac McCarthy, Viscount Muskerry, a descendant of Dermot McCarthy Mor, king of Munster and a sister of Donough, second Earl of Clancarty who was outlawed in the time of Charles II. On that slender connection the Earldom of Clancarty was regranted to the Trench family after the Union.
