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

Early Origins of the Sweney family

The surname Sweney 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.

A great mass of Ireland's native population left the island in the 19th century, seeking relief from various forms of social, religious, and economic discrimination. This Irish exodus was primarily to North America. If the migrants survived the long ocean journey, many unfortunately would find more discrimination in the colonies of British North America and the fledgling United States of America. These newly arrived Irish were, however, wanted as a cheap source of labor for the many large agricultural and industrial projects that were essential to the development of what would become two of the wealthiest nations in the western world.
