Docherty, Dorrity, Dougharty, Dougherty, O’ Docherty, O’ Dogherty, Ó Dochartaigh
The Doghertys originated in Co. Donegal, and their name is one of the oldest hereditary surnames in Ireland today. They are descended from Niall of the Nine Hostages, King of Ireland in the fourth century. Their stronghold is Co. Donegal in the northern province of Ulster, where they were powerful chiefs until the execution of Cahir O’ Doherty in the seventeenth century. The name comes from the word “dochartach” which means ‘unlucky’ or ‘hurtful’. Doherty is the fifteenth most numerous in Ireland, and first and second most numerous respectively in counties Derry and Donegal.
