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

Early Origins of the Onneile family

The surname Onneile 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.

Migration of the Onneile family

Irish families left their homeland in astonishing numbers during the 19th century in search of a better life. Although individual reasons vary, most of these Irish families suffered from extreme poverty, lack of work opportunities, and exorbitant rents in their homeland. Many decided to travel to Australia or North America in the hopes of finding greater opportunities and land. The Irish immigrants that came to North America initially settled on the East Coast, often in major centers such as Boston or New York. But like the many other cultures to settle in North America, the Irish traveled to almost any region they felt held greater promise; as a result, many Irish with gold fever moved all the way out to the Pacific coast. Others before that time left for land along the St. Lawrence River and the Niagara Peninsula, or the Maritimes as United Empire Loyalists, for many Irish did choose to side with the English during the American War of Independence. The earliest wave of Irish migration, however, occurred during the Great Potato Famine of the 1840s. An examination of early immigration and passenger lists has revealed many people bearing the Onneile name: 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.
