Etymology of O'Neil

What does the name O'Neil mean?

Irish names tend to vary widely in their spelling and overall form. The original Gaelic form of the name O'Neil is Ó Néill, which means descendant of Niall, a personal name of Irish origin, thought to mean "champion." 1

"Of the very great antiquity of this distinguished name and family there can be no doubt." 2

O'Neil Coat of Arms Creation

Two brothers of the race of Colla Uais saw the Isle of Islay from their native Ireland, and both, at the same time, resolved to possess it. Each got his birlinn ready with its full comple-ment of men, and the race began. When within a short distance of landing, one galley was a length ahead ; whereupon the brother in the galley behind, seeing that the race was about to be won by the other, placed his left hand on the gunwale and, with his own sword, cut it off and threw it ashore, saying as he did so, " Tha m' fhuil agus m' fheoil air tir romhad" ("My flesh and my blood are ashore ahead of you "). 3

Early Origins of the O'Neil family

The surname O'Neil was first found in County Tyrone (Irish: Tír Eoghain), the ancient territory of the O'Neills, now in the Province of Ulster, central Northern Ireland, and County Clare where O'Neill was chief of Clan Dalvy and of Tradree, a district in the barony of Inchiquinn. In the 10th century, a branch of this family went to Limerick to assist in the expulsion of the Danes.

After one victorious occasion they wore green boughs in their helmets and on their horses' heads signifying their victory.

O'Neil Spelling Variations

People who were accounted for by scribes and church officials often had their name recorded many different ways because pronunciation was the only guide those scribes and church officials had to go by. This resulted in the problem of one person's name being recorded under several different variations, creating the illusion of more than one person. Among the many spelling variations of the surname O'Neil that are preserved in archival documents are O'Neill, Neal, Neale, Neales, Neil, Nihill, Niell, O'Nail, O'Neil, O'Niel and many more.

O'Neil migration to the United States +

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. Early immigration and passenger lists indicate many people bearing the O'Neil name:
