Origin of the Gorman name
Mac Gormáin were lords of Ui Bairche, barony of Slievemargy, south-east Leix. Soon after the Anglo-Norman invasion they were driven out and settled in Monaghan and in Ibrickan, West Clare; the head of the Clare branch was marshal of O'Brien's forces. Ó Gormáin was a separate, rare name; in Connacht Gorman can also stand for Ó Gormghail.[1][2][3]

Gorman surname: questions
What does the surname Gorman mean?
Woulfe derives it mainly from Mac Gormáin, 'son of Gormán', Gormán being a diminutive of gorm, blue. Ó Gormáin, 'descendant of Gormán', is a separate rarer name.[1][2]
Is it Gorman, O'Gorman or MacGorman?
Woulfe calls MacGorman 'the more correct form', still kept in the North, and says O'Gorman was adopted in modern times, 'but incorrectly', by some of the name in Munster.[1]
Where in Ireland is the Gorman name from?
Mac Gormáin were lords of Ui Bairche in Slievemargy (Leix) before moving to Monaghan and West Clare. In 1890 Gorman births were chiefly in Antrim, Dublin and Tipperary, and O'Gorman births in Clare.[1][5][6]
Is Gorman always from the same family?
No. Woulfe says Gorman can also disguise Ó Gormghail, a Mayo and Roscommon name, and Ó Gormóg of Carra, Mayo, besides the rare Ó Gormáin.[2][3][4]
