From Ó Broin — descendant of Bran. The eponymous Bran was Bran mac Máelmórda, king of Leinster, who died in 1052. His descendants were driven from their flatter ancestral lands in northern Wicklow and southern Dublin by the Anglo-Norman conquest of the 1170s and took refuge in the Wicklow Mountains, where they remained an unconquered lordship for four hundred years. Anglicised forms include Byrne, O'Byrne and Beirne; the Gaelic Ó Broin survived in Irish-speaking Wicklow into the 19th century.
The history of Byrne
The Ó Broin took to the high country south of Dublin after the Norman conquest and held it as effectively independent territory for the next four centuries. Their stronghold was Glenmalure — a deep glaciated glen on the eastern flank of Lugnaquilla, accessible only by a single track and impossible to take with conventional cavalry — and from there they raided the Pale within sight of the city walls of Dublin. Together with their kinsmen the Ó Tuathail (O'Tooles) of Imaal, they made the southern boundary of the Pale a fortified line for the whole later medieval period.
Fiach McHugh O'Byrne (Fiach mac Aodha Ó Broin, c.1544–1597) is the most consequential bearer. Lord of Ballinacor in Glenmalure, he wiped out an English expedition under Lord Deputy Grey de Wilton at the battle of Glenmalure in August 1580 — eight hundred English troops killed in one afternoon, in what Grey himself called 'a great heap'. He sheltered Hugh O'Donnell after Red Hugh's escape from Dublin Castle in January 1592, and again in 1597 (see the O'Donnell page). He was killed at Ballinacor in May 1597 by an English expedition that finally brought him down — but only just, and by surprise.
Gabriel Byrne (b. 1950), the actor; Donn Byrne (1889–1928), the New York-Irish novelist; David Byrne of Talking Heads (b. 1952), of Scottish-Byrne descent — all from the same Wicklow surname pool. The Byrnes today number around forty thousand on the island, with by far the highest density still in the original Wicklow heartland.
