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

Early Origins of the Sweeney family

The surname Sweeney 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.

United States Sweeney migration to the United States +

In the 19th century, thousands of Irish left their English-occupied homeland for North America. Like most new world settlers, the Irish initially settled on the eastern shores of the continent but began to move westward with the promise of owning land. The height of this Irish migration came during the Great Potato Famine of the late 1840s. With apparently nothing to lose, Irish people left on ships bound for North America and Australia. Unfortunately a great many of these passengers lost their lives - the only thing many had left - to disease, starvation, and accidents during the long and dangerous journey. Those who did safely arrive in "the land of opportunities" were often used for the hard labor of building railroads, coal mines, bridges, and canals. The Irish were critical to the quick development of the infrastructure of the United States and Canada. Passenger and immigration lists indicate that members of the Sweeney family came to North America quite early:
