History of the McDonagh name

McDonagh, Mac Donnchadha, means 'son of Donnchadh' and arose independently in several places, but the chief sept was a branch of the MacDermots who ruled Tirerrill and Corran in County Sligo from their castle at Ballymote. It was in their house that the Book of Ballymote, one of the great medieval Irish manuscripts, was compiled around 1390 under McDonagh patronage. A second concentration of the name grew up in Connemara and east Galway, where McDonaghs remain among the most numerous families. The spelling varies endlessly, with McDonough favoured in America, but all forms are the one name.
