Where did the Irish Clancy family come from? What is the Irish Clancy family crest and coat of arms? When did the Clancy family first arrive in the United States? Where did the various branches of the family go? What is the Clancy family history?

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


Names written in official documents were generally spelt as they sounded, leading to the problem of one name being recorded under several different variations, creating the illusion in records of more than one person. Among the many spelling variations of the surname Clancy that are preserved in documents of the family history are Clancy, Clancey, Clanchey, Clanchy, Clansey and many more.

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]

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 Clancy:
