The Irish name Gallagher has a long Gaelic heritage to its credit. The original Gaelic form of the name Gallagher is Ó Gallchobhair, derived from the word "gallchobhar," which means "foreign help."

Early Origins of the Gallagher family

The surname Gallagher was first found in County Donegal (Irish: Dún na nGall), northwest Ireland in the province of Ulster, sometimes referred to as County Tyrconnel, but claim descent from a warrior named "Gallchobhar" and held lands in the baronies of Raphoe and Tir Hugh. They held a castle at Ballyshannon and at one time also held the castle of Lifford.

The Sept's chiefs were the traditional Marshals in the O'Donnells' military forces from the 14th to 16th centuries. The main branch of the family was based at Ballybeit and Ballynaglack.
