Ó GALLCHOBHAIR—IO Galleghure, O'Gallagher, Gallagher, Gallaher, Gallogher, Gollagher, &c.; 'descendant of Gallchobhar' (foreign help); the name of a numerous and once powerful family in Tirconnell, who derive their descent from Maolchobha, King of Ireland in the 7th century. As marshalls of O'Donnell's forces, the O'Gallaghers took a prominent part in all the military movements of Cinel Conaill during the 14th and subsequent centuries. Many of them were distinguished as Bishops of Raphoe and Derry. The name was sometimes shortened to Ó Gallchú, which see.
