Early Origins of the MacConaghy family

The surname MacConaghy was first found in County Donegal with the MacSweenys. That 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.'

United States MacConaghy migration to the United States +

The 18th century saw the slow yet steady emigration of Irish families to British North America and the United States. Those early Irish settlers that left their homeland were typically moderately well off: they were enticed by the promise of a sizable plot of land. However, by the 1840s, this pattern of immigration was gone: immigrants to North America were seeking refuge from the starvation and disease that the Great Potato Famine of that decade brought. The great numbers of Irish that arrived to the United States and the soon to be Canada were instrumental in their quick development as powerful industrial nations. An examination of early immigration and passenger lists uncovered many early immigrants bearing the name MacConaghy:
