Richard Bagwell, Ireland under the Tudors, with a Succinct Account of the Earlier History…
“ For nearly two hundred years the history of Ireland is in the main a history of Celtic gains at the expense of Anglo-Normans and Englishmen; if, indeed, anarchy can rightly be accounted gain to any race or community of men.The last Earl of Ulster is murdered, 1333. The De Burgos and other Anglo-Normans assume Irish names and habits.In 1326 the Red Earl of Ulster retired into the monastery of Athassel, where he died soon afterwards. His great power descended to his grandson William, who was murdered at or near Carrickfergus in 1333 by the Mandevilles and other Ulster colonists. ”
