Today's Irish surnames are underpinned by a multitude of rich histories. The name O'Donolly 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'Donolly family

The surname O'Donolly 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'Donolly family

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'Donolly name: 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.
