O'Donoghue of the Glens

The O'Donoghue of the Glens (Irish: Ó Donnchadha na nGleann), Prince of Glenflesk, is the hereditary chieftain of his sept of the Kerry Eóganacht, Munster, Ireland.

There was much internecine war during the time of Auliffe Mór, when the O'Brien dynasty of Thomond were battling (ultimately unsuccessfully) for control of all Munster.

He completed the cathedral of Achadh Dá Eó on the heights overlooking the Lakes of Killarney just prior to his death in 1158.

[4] It was during a campaign in Waterford that same year that Auliffe Mór was killed on the bank of the River Suir by Muircheartach son of Toirdhealbhach Ó Briain,[4] well east of the MacCarthy territory, which indicates the scope of his efforts to maintain the sovereignty of Desmond.

He lamented: In 1652 the castle was hit with newly employed cannon by General Ludlow's army and partially destroyed.

After the Act of Settlement, one of Geoffrey's most often quoted stanzas is: Glenflesk itself was known as the haunt of outlaws and tories, and in popular parlance the English referred to it as the 'Robbers Glen'.

[10] They became notorious as the 'Dangerous O'Donoghues' who constantly harassed the English colony brought into the Killarney region by the undertaker Browne family, known as the Earl of Kenmare.

'[8] Throughout the centuries, the Glens family managed to retain their title and territory, and eventually built Killaha House near their ruined castle.
