Origin of the Byrne name
Woulfe: named from Bran, son of Maolmórdha, King of Leinster (died at Cologne, 1052). Their first patrimony, Ui Faolain in north Kildare, was lost soon after the Anglo-Norman invasion; they took refuge in the Wicklow mountains, in Crioch-Bhranach. A junior branch, the Gaval-Rannall (Ranelagh), held Ballinacor.[1]

Byrne surname: questions
What does the surname Byrne mean?
Woulfe gives Byrne as a form of Ó Broin, 'descendant of Bran', a personal name he glosses as 'raven'.[1]
Are Byrne and O'Byrne the same name?
Yes. Woulfe lists O'Byrne, Byrne and Byrnes as English forms of Ó Broin. In the 1890 birth indexes Matheson counted 734 Byrne entries but only 8 spelt O'Byrne.[1][2][5]
Where in Ireland is the Byrne name from?
Woulfe says the family first held north Kildare and then the Wicklow mountains, and that the name is now very common in Leinster. In 1890 Byrne was principally found in Dublin, Wicklow, Wexford and Louth, with many also in Carlow, Kildare and Kilkenny.[1][2]
Who was Fiagh MacHugh O'Byrne?
According to Webb, he was chief of the Gaval-Rannall O'Byrnes, lived at Ballinacor in Glenmalure, defeated Lord Grey there in 1580 and was killed in May 1597.[3]
