- Origins Available:
 Ireland Irish names tend to vary widely in their spelling and overall form. The original Gaelic form of the name Oneile 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 Early Origins of the Oneile familyThe surname Oneile 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.

 Oneile migration to the United States | + |
The 19th century saw a great wave of Irish families leaving Ireland for the distant shores of North America and Australia. These families often left their homeland hungry, penniless, and destitute due to the policies of England. Those Irish immigrants that survived the long sea passage initially settled on the eastern seaboard of the continent. Some, however, moved north to a then infant Canada as United Empire Loyalists after ironically serving with the English in the American War of Independence. Others that remained in America later joined the westward migration in search of land. The greatest influx of Irish immigrants, though, came to North America during the Great Potato Famine of the late 1840s. Thousands left Ireland at this time for North America, and those who arrived were immediately put to work building railroads, coal mines, bridges, and canals. In fact, the foundations of today's powerful nations of the United States and Canada were to a larger degree built by the Irish. Archival documents indicate that members of the Oneile family relocated to North American shores quite early:
