However, whether "caidh" denotes warrior as has been asserted is unknown.

Early Origins of the O'Clanshie family

The surname O'Clanshie 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'Clanshie family

The English-ruled Ireland of the late 18th and 19th centuries featured a rapidly increasing population and an agricultural-based economy. This combination proved to be disastrous in the 1840s after a couple of failed potato harvests. Thousands died of disease and starvation, and thousands more left the country, often bound for North America. Those that survived the journey to North America were put to work building the bridges, canals, roadways, and railways needed for the development of an industrial society. Those Irish, although often despised by those already established in North American cities and towns, played an instrumental role in making Canada and the United States the powerful and wealthy nations that they are today. An examination of early immigration and passenger lists has shown many immigrants bearing the name O'Clanshie: 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.
