The original Gaelic form of McDuffie was Ó Dubhthaigh. The first portion of the name is the word "dubh," which means "black," while the second portion is likely an obsolete Irish forename. 1

The sept claim descent from the ancient Heremon Kings of Ireland. Through O'Conner Faley, Lords of Offaley (now Offaly), they descend from "Cahir Mor, King of Leinster in the beginning of the second century. He divided his great possessions amongst his thirty sons in a Will called 'The will of Cahir More,' contained in the 'Book of Leacan' and in the 'Book of Balymote.' His posterity formed the principal families in Leinster." 2 O'Duffy was listed as one of these such families.

Early Origins of the McDuffie family

The surname McDuffie was first found in Connacht (Irish: Connachta, (land of the) descendants of Conn), where they held a family seat from very ancient times, and were one of the many families descended from the great Kings of Ireland called the "Three Collas." Descending from the Clan Colla was Duffy, Lord of Fermanagh.

However, "there are several distinct septs of O'Duffy. One belongs to the parish of Lower Templecrone in the diocese of Raphoe, Co. Donegal, the patron saint of which is the seventh century Saint Dubhthach, or Duffy. The Connacht sept, the centre of whose territory was Lissonnuffy or Lissduffy near Strokestown, named after them, was remarkable for the number of distinguished ecclesiastics it produced." 3

Without a doubt, the oldest records of the family include: Muireadach Ó'Dubthaigh (Murdagh O'Duffy) (1075-1150), Archbishop of Tuam in the county of Connaught and Cadhla Ó'Dubthaigh, (Cele O'Duffy) Archbishop of Tuam, Ambassador to Henry II in 1175. 3

The Monaghan branch of the family were principally found in Attyduffy or Attyduff 2 and "modern statistics show that it is now most numerous name in Co. Monaghan." 1

United States McDuffie migration to the United States +

A massive amount of Ireland's native population left the island in the 19th century for North America and Australia in hopes of finding more opportunities and an escape from discrimination and oppression. A great portion of these migrants arrived on the eastern shores of the North American continent. Although they were generally poor and destitute, and, therefore, again discriminated against, these Irish people were heartily welcomed for the hard labor involved in the construction of railroads, canals, roadways, and buildings. Many others were put to work in the newly established factories or agricultural projects that were so essential to the development of what would become two of the wealthiest nations in the world. The Great Potato Famine during the late 1840s initiated the largest wave of Iris immigration. Early North American immigration and passenger lists have revealed a number of people bearing the name McDuffie or a variant listed above:
