Irish names tend to vary widely in their spelling and overall form. The original Gaelic form of the name McSweeny is Mac Suibhne, which is derived from the word "suibhne," which means "pleasant."

Early Origins of the McSweeny family

The surname McSweeny was first found in County Donegal (Irish: Dún na nGall), northwest Ireland in the province of Ulster, sometimes referred to as County Tyrconnel. The name is derived from Suibhne O'Neill, who was a chieftain in Argyll, Scotland. His descendants migrated to Ireland as gallowglasses (mercenaries) prior to 1267. The three great septs of this name finally established themselves in Tirconnell in 14th century; they were known as MacSweeney Fanad, MacSweeney Banagh, and MacSweeney na dTuath, who were commonly referred to as 'MacSweeney of the Battleaxes.' They later became attached to the MacCarthys in the south and acquired their own territories and castles in Muskerry in County Cork.

Those who lived to see North American shores were instrumental in the development of the growing nations of Canada and the United States.
