The Sweeney Name


Peter Cuffley has researched the ancient origins of our Sweeney branch.

By way of summary, The Mac Suibhnes- anglicised as MacSween(e)y, McSween(e)y, Swee(e)ny, MacSween, with up to 30 earlier variants, such as McSwiny, M'Sweeny, etc - were fierce, heavily armed fighting men, emanating from the Scottish Islands and Highlands. 

The MacSweeneys, probably crossing over from Argyle, arrived in County Donegal in the 14th century, according to most authorities, where they were hired by chiefs such as the O Donnell. Doe Castle was the strongold of the MacSweeneys in County Donegal. Read more at http://tomgallen.com/2013/12/doe-castle-stronghold-of-the-macsweeneys/.

This picture, from a 1924 publication called 'Hutchinson's Britain Beautiful' (Volume 2), shows McSwyne's tombstone in Doe Castle.


From Donegal, they travelled to and settled in Cork, Sligo and Tipperary.

Our Sweeney family springs from the group who travelled to Tipperary to fight for the Butlers. There were already Sweeney families in the Barony of Ikerrin in the 16th century. Cullahill was in that area.
