The surname is one of the many Irish surnames rooted in Gaelic language native to Ireland. The original Gaelic form of the name O'Creagh is Craobhach, derived from the word "craobh," which means "branch." 1

Early Origins of the O'Creagh family

The surname O'Creagh was first found in County Clare (Irish: An Clár) located on the west coast of Ireland in the province of Munster, where this ancient Irish family was descended from King Niall of "the Nine Hostages," the great General King, who in turn was descended from the Heremon line of Irish Kings.

The Creaghs were one of the celebrated septs and leading gentry of the County Clare. They were a branch of the O'Neills of County Clare and tradition has it that they carried green branches with them into battle against the Norsemen at Limerick.

Their name is derived from the Irish surname Craobhach, which is the adjective formed from the noun "craob," a branch. Other names are derived from this source as well such as Cray, the anglicized form of O Craoibhe meaning "descendant of Craobhach."

Migration of the O'Creagh family

A massive amount of Ireland's native population left the island in the 19th century for North America and Australia in hopes of finding more opportunities and an escape from discrimination and oppression. A great portion of these migrants arrived on the eastern shores of the North American continent. Although they were generally poor and destitute, and, therefore, again discriminated against, these Irish people were heartily welcomed for the hard labor involved in the construction of railroads, canals, roadways, and buildings. Many others were put to work in the newly established factories or agricultural projects that were so essential to the development of what would become two of the wealthiest nations in the world. The Great Potato Famine during the late 1840s initiated the largest wave of Iris immigration. Early North American immigration and passenger lists have revealed a number of people bearing the name O'Creagh or a variant listed above: Carmelo Creagh who settled in Philadelphia in 1878; along with Richard and Thomas; Isabella Creag settled in Pennsylvania in 1772; Michael Creier settled in Philadelphia in 1741..
