Show ContentsDennely History, Family Crest & Coats of Arms

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

The surname Dennely 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 Dennely family

Thousands of Irish families left for North American shores in the 19th century. These people were searching for a life unencumbered with poverty, hunger, and racial discrimination. Many arrived to eventually find such conditions, but many others simply did not arrive: victims of the diseased, overcrowded ships in which they traveled to the New World. Those who lived to see North American shores were instrumental in the development of the growing nations of Canada and the United States. A thorough examination of passenger and immigration lists has disclosed evidence of many early immigrants of the name Dennely: 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.
