What does the Gallagher name mean?

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.
