Hostilities broke out in Tirconnell between Hugh, son of Donnel Oge,
and Turlough, his brother, concerning the lordship, so that a great

ecclesiastical property. Turlough was afterwards deposed, and banished
from Tirconnell to the Kinel-Owen and the Clann-Donnell. AFM

1303


Turlough, the son of Donnell Oge O'Donnell usually called Turlough of
Cnoc-an-Madhma (hill of the defeat), Lord of Tirconnell, a warlike 
tower of protection in battle, and the Cuchullin of the Clann-Daly in
valeur, was slain by his brother, Hugh, after a long war, during which
much of their country was spoiled between them in every direction; and
great numbers of the Kinel-Owen, of the chiefs of the English of the
north, and of the Kinel-Connell themselves, were slaughtered along with
him. Among these were two grandsons of the Ferleighin (Lector)
O'Donnell. After this, Hugh enjoyed the lordship of Tirconnell in
hapiness and prosperity as long as he lived. AFM
