History of the Hegarty name

Hegarty comes from O hEigceartaigh, meaning 'descendant of the unjust or hard one', from eigceart, unjust. The sept originated in County Donegal and spread into Derry and Tyrone, becoming one of the most numerous surnames in the north-west of Ireland. A branch also settled in Munster, particularly Cork, from an early date, giving the name a second, separate stronghold. Despite the harsh literal meaning of the root word, such names typically referred to a distant ancestor's disposition or a nickname rather than describing the family as a whole. Hegarty remains heavily concentrated in Derry and Donegal today, alongside its long-established Cork branch.
