From Ó Gallchobhair — descendant of Gallchobhar. The personal name Gallchobhar splits as gall (foreign, stranger) + cobhar (helper / supporter), commonly read as 'foreign helper' — an honorific applied originally to a man who had brought foreign warriors into the service of a chief. The eponymous Gallchobhar was a tenth-century kinsman of the Ó Domhnaill (O'Donnell) of Tír Chonaill. The Gallaghers were the senior cadet branch of the O'Donnells throughout the medieval and early-modern period and the hereditary cavalry commanders of the Tír Chonaill household troops.
The history of Gallagher
Gallagher is the most common surname in Donegal by a clear margin — and outside Donegal, the surname is essentially the surname of the Donegal-descended diaspora. Through the 14th, 15th and 16th centuries the Gallaghers were the marshals of the O'Donnell cavalry — the kind of dedicated military caste that the Gaelic system produced in several of the great northern lordships. Two Gallaghers were bishops of Raphoe in the early-modern period; many more were officers in the great O'Donnell campaigns of the Nine Years' War.
After the Plantation of Ulster the family dispersed, but unusually for a Gaelic Donegal name, the Gallaghers held in Donegal in significant numbers throughout the Plantation period and beyond — the surname is among the very few principal Gaelic surnames whose modern density still corresponds almost exactly to its medieval territorial heart. Rory Gallagher (1948–1995), the Donegal-via-Cork blues guitarist, is the most internationally famous bearer; Liam and Noel Gallagher of Oasis are from a Manchester-Mayo-Gallagher line of late-19th-century Irish emigration.
