Early Origins of the O'Clansy family

The surname O'Clansy 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'Clansy family

In the late 18th century, Irish families began emigrating to North America in the search of a plot of land to call their own. This pattern of emigration grew steadily until the 1840s when the Great Potato Famine of the 1840s cause thousands of Irish to flee the death and disease that accompanied the disaster. Those that made it alive to the shores of the United States and British North America (later to become Canada) were, however, instrumental in the development of those two powerful nations. Many of these Irish immigrants proudly bore the name of O'Clansy: 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.
