O'Gorman - Irish Surname Origin & Meaning

Irish form: Ó Gormáin

Meaning: “noble, blue”

Traditional stronghold: Clare, Monaghan

Pronunciation: oh-GOR-man; Irish Mac Gormáin: mock GOR-mawn

History of the O'Gorman name

Curiously, most O'Gormans are really MacGormans. The sept was Mac Gormáin, from gorm ('blue', by extension 'noble'), lords of Slievemargy on the Laois-Carlow border and part of the Uí Bairrche of Leinster. Dispossessed early in the Anglo-Norman invasion, they migrated in two directions: to Ibrickan in west Clare, where they became marshals to the O'Briens of Thomond and famous for hospitality, and to Monaghan. When Gaelic prefixes were resumed in the nineteenth century, the historically correct Mac was widely replaced by O, a fashion often credited to the vanity of the Chevalier Thomas O'Gorman, an eighteenth-century genealogist in French service. Clare, Tipperary and Monaghan remain the name's heartlands.
