Early Origins of the Onneill family
The surname Onneill 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.

Migration of the Onneill family
Death and immigration greatly reduced Ireland's population in the 19th century. For the native Irish people poverty, hunger, and racial prejudice was common. Therefore, thousands left their homeland to seek opportunity in North America. Those who survived the journey and the quarantine camps to which they arrived, were instrumental towards building the strong developing nations of the United States and the future Canada. By far, the largest influx of Irish settlers occurred with Great Potato Famine during the late 1840s. These were employed as construction or factory workers. An examination of passenger and immigration lists has shown early immigrants bearing the name Onneill: Captain James Neale (1615-1684) who arrived about 1635 in Maryland and received 1,000 acres of land, many of his descendants became Jesuit priests; Edward Neal settled in Boston in 1849.
