Gallagher is an Irish surname. It originates from the Irish noble Gallagher family of County Donegal, Ireland, meaning âÂÂdescendant of the foreign helperâÂÂ. The name Gallagher is an anglicization of the Irish surname àGallchobhair, àGallchobhoir (or two alternative spelling forms, àGallchóir and àGallachóir), these being masculine forms; the corresponding feminine forms are NàGhallchobhair (newer forms NàGhallchóir and NàGhallachóir). At least 30 recorded alternate variants exist, including O'Gallagher, Gallacher, Gallager, Gallaher, Gallocher, Galliher, Gollaher, Gollihar and Gallahue.
The earliest recorded incidence of the name is in a fragment of a manuscript currently in the Royal Library of Brussels, which states the name "Gallchubhair". A similarly earlier mention occurs in the Annals of the Four Masters, where it is recorded that Mael Cobo ÃÂi Gallchobhar, Abbot of Scrin Adamnain, died in 1022 AD. Gallchobhar was the one given the role of founding father of the clan at the advent of widespread surname usage in Ireland, which began around the 10th century.
As with other modern Irish last names, àGallchóir similarly appears to be a conjoined compound word.
Most Gallaghers are found in the Americas, where approximately 60% of Gallaghers originate. The United States is the home to 55% of Gallaghers. Gallagher is also the most common surname in County Donegal (Dún na nGall means "fort of the foreigner"), and thus is very common in Derry, and is the fourteenth-most-common by birth records in Ireland. In the United States, it was ranked by the 2020 US Census as the 482nd most common name. According to Professor Edward MacLysaght, in the mid-20th century Gallagher was one of the most common Irish surnames, most of the recorded births being located in the northern province, Ulster, and the western province, Connacht, with the majority being recorded in the homeland of the septâÂÂCounty Donegal in Ulster. In 1890 it was ranked the 12th-most-common surname in Ireland, while in 1996 it was 20th.
