Today's Irish surnames are underpinned by a multitude of rich histories. The name O'Donnelly originally appeared in Gaelic as Ó Donnghaile, derived from the words "donn," which means "brown," and "gal," which means "valor." 1

Early Origins of the O'Donnelly family

The surname O'Donnelly was first found in County Donegal. Later, the sept expanded eastward and became based at Ballydonnelly in the county of Tyrone. The name continues to be common in this area of Ireland today.

The name is believed to be directly descended from King Niall of the Nine Hostages, the great Irish general/king who died by the River Seine in France about 365 A.D., after soundly defeating the Romans and being instrumental in their return to the south. Niall made King Arthur's exploits seem rather small by comparison.

The Donnelly chief was always elected Chief Marshall of the O'Neill forces and their exploits have filled the pages of Irish history compiled by the Four Masters. They are a part of the great Clann Eoghan(Owen).

They claim to be seventeenth in descent from the great King Niall, and their territories were at Ballydonnelly in County Tyrone.

Migration of the O'Donnelly family

In the 19th century, thousands of Irish left their English-occupied homeland for North America. Like most new world settlers, the Irish initially settled on the eastern shores of the continent but began to move westward with the promise of owning land. The height of this Irish migration came during the Great Potato Famine of the late 1840s. With apparently nothing to lose, Irish people left on ships bound for North America and Australia. Unfortunately a great many of these passengers lost their lives - the only thing many had left - to disease, starvation, and accidents during the long and dangerous journey. Those who did safely arrive in "the land of opportunities" were often used for the hard labor of building railroads, coal mines, bridges, and canals. The Irish were critical to the quick development of the infrastructure of the United States and Canada. Passenger and immigration lists indicate that members of the O'Donnelly family came to North America quite early: Catherine and Hugh Donnelly who settled in New York in 1803; Hugh Donnelly settled in Belfast, Maine in 1820; Bryan, Peter and Thomas Donnelly landed in America in 1763.
