The Irish surnames in use today are underpinned by a multitude of rich histories. The name O'Clanchie originally appeared in Gaelic as Mac Fhlannchaidh. The exact meaning of this name is undetermined; it can be translated as "son of Fhlannchadh," where "flann" means "reddish" or "ruddy." However, whether "caidh" denotes warrior as has been asserted is unknown.

Early Origins of the O'Clanchie family

The surname O'Clanchie was first found in Counties Clare and Leitrim. The more important of the two MacClancy septs were a branch of the MacNamaras and were from the north of County Clare, where they gave their name to Cathermacclancy. They traced their lineage from the Heber kings, and provided hereditary brehons (judges) to the O'Briens. They were most numerous in County Clare and the neighboring counties of Galway and Tipperary. The other sept of MacClancys were indigenous to Leitrim, and were Chiefs of Darty or Rosclogher. 1

Migration of the O'Clanchie family

Irish families began to immigrate to British North America and the United States in the 18th century, but the greatest influx of Irish immigrants came during the Great Potato Famine of the late 1840s. The earlier settlers came to North America after a great deal of consideration and by paying relatively high fees for their passage. These settlers were primarily drawn by the promise of land. Those later settlers that came during the 1840's were trying to escape the conditions of poverty, starvation, disease, and death that had stricken Ireland. Due to the enormity of their numbers and the late date of their arrival, these immigrants primarily became hired laborers instead of homesteading settlers like their predecessors. An exhaustive search of immigration and passenger lists has revealed many Irish immigrants North America bearing the name O'Clanchie: Cornelius Clancey who settled in Barbados in 1680 with his wife and servants; Richard Clanchy settled in New York with his wife and eight children in 1820.
