Ó DOCHARTAIGH—IO Doghartie, O'Dogherty, O'Dougherty, O'Doherty, Dogherty, Dougherty, Doherty, &c.; 'descendant of Dochartach' (hurtful, disobliging). The O'Dohertys, who are a branch of the Cinel Conaill and of the same stock as the O'Donnells, were originally chiefs of Cinel Enna and Ard Miodhair, now anglicised Ardmire, in the barony of Raphoe, but about the beginning of the 15th century, they became lords of Inishowen and one of the most powerful families of Tirconnell, a position which they retained down to the reign of James I, when, after the rebellion of Sir Cahir O'Dogherty, their possessions were confiscated and granted to Sir Arthur Chichester. The O'Doghertys are now one of the most numerous of Irish families.
