The Irish surnames in use today are underpinned by a multitude of rich histories. The name Clansy 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 Clansy family

The surname 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 Clansy family

Ireland saw an enormous decrease in its population in the 19th century due to immigration and death. This pattern of immigration began slowly in the late 18th century and gradually grew throughout the early portion of the 19th century. However, a dramatic increase in the country's immigration numbers occurred when the Great Potato Famine struck in the 1840s. The early immigrants to North America were primarily destined to be farmers tending to their own plot of land, those that came later initially settled within pre-established urban centers. These urban immigrants provided the cheap labor that the fast developing United States and soon to be Canada required. Regardless of their new lifestyle in North America, the Irish immigrants to the United States and Canada made invaluable contributions to their newly adopted societies. An investigation of immigrant and passenger lists revealed many Clansys: 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.
