Conor O'Brien, 3rd Earl of Thomond - Irish Biography

O'Brien, Conor, 3rd Earl of Thomond, in 1570 broke out into rebellion, was defeated, and passed over into France; but was afterwards received back into favour by Elizabeth, and returned to Ireland with commendatory letters to the Council. In October 1577, after another period of civil war, he visited the Queen, and again obtained several advantages for himself and his descendants. He died in 1580, aged 46, and within five years Thomond was completely settled into counties and shire ground, all old rights and customs abolished by law, circuits established, and the powers of the O'Briens restricted to those enjoyed by the nobility in England.
