"Pinkman Cluainín-Uí-Ruairc = O’Rourke’s meadow land. This was the old name of the place. The townland of Clooneen is beside the town. Manorhamilton comes from Sir Fredereick Hamilton, who erected a castle there in the reign of Elizabeth. This castle was considered, in its time, “the largest, strongest and finest in the county as well it might! Hamilton was detested by the people among whom he lived. He was said to have offered £5 for every Breifnian’s head that contained the rebellious notions of an O’Rourke or a Mac Glancy. His castle was burned, it is stated, by a family name McLoughlin, who detested his name and his power – and perhaps with very good reason. "

"LSO: In Manorhamilton is an old Castle in ruins, which was erected by Sir Frederick Hamilton, who, the people say, was a bloody murderer; but the stories told of him are evidently the emanations of minds that detested him as their conqueror, and as a man who did not care if the devil had all the Mag Glanchies. He was in the habit of giving £5 for every Breifnian head which had contained the nobly rebellious notions of an O’Rourke or a Maglanchy. His Castle is said to have been set on fire by a family of the name of Mag Loughlin, who detested his name and his power; after the burning of his Castle he passed over to Scotland, where he shortly after died of the lousy disease! A disease to which many great and illustrious potentates have, in the recollection of history, fallen victims 131/257. "

• “Clooneen is in the parish of Killasnet, but the greater part of Manorhamilton is in the townland of Manorhamilton, which is separated from Clooneen by the Owenbeg river…. It would seem from the terms of a grant made to Sir Frederick Hamilton in the sixth year of Charles I that the old name of the townland of Manorhamilton was ‘Clonemullen.’…Cluain Maoláin, the meadow of the hillock.’ After the rise of the town Irish speakers adopted the new name, turning ‘manor’ into ‘baile.’’’…In our own day Irish speakers in Glangevlin, Co. Cavan, call the town Baile Hamaltuin.” (Éigse V, 171-172)
