The Irish surnames in use today are underpinned by a multitude of rich histories. The name Flaherdy originally appeared in Gaelic as "O Flaithbheartaigh," which means "bright ruler."

Early Origins of the Flaherdy family

The surname Flaherdy was first found in Connemara (Irish : Conamara), which derives from Conmhaicne Mara (meaning: descendants of Con Mhac, of the sea)), County Galway in Connacht where the name claims descent from Flaithbertaigh Ua Flaithbertaigh, King of Connacht, who died 1098. Flaithbertaigh was the first bearer of the surname O'Flaherty, and was Lord of Maigh Seola in what is now County Galway. 1

"The O'Flahertys were originally located in the Barony of Clare, County Galway, but in the thirteenth century, having been expelled from this territory, they settled in the Barony of Moycullen, and were styled Lords of lar Conacht or West Connaught. A large number of the Flahertys are now to be found in the Baronies of Moycullen, Ross, and Ballinahinch, in County Galway." 2

Another source gives this background about the family: "This family, whose tribe name was Muintir Murchadha, traced their descent from Flaibheartach, twenty-second in descent from Eochaidh Muighmeadhon, king of Ireland, who died in 366. They were at first settled in Magh Seola, to the east of Lough Corrib, but in the thirteenth century were driven from their original home by the O'Connors, and conquered a new territory in West Connaught from Lough Corrib to the sea. There were several septs of the clan." 3

Migration of the Flaherdy family

A massive wave of Irish immigrants hit North America during the 19th century. Although many early Irish immigrants made a carefully planned decision to leave left Ireland for the promise of free land, by the 1840s immigrants were fleeing a famine stricken land in desperation. The condition of Ireland during the Great Potato Famine of the late 1840s can be attributed to a rapidly expanding population and English imperial policies. Those Irish families that arrived in North America were essential to its rapid social, industrial, and economic development. Passenger and immigration lists have revealed a number of early Irish immigrants bearing the name Flaherdy: James Flaherty who landed in Virginia in 1651; followed James Flaharty in 1651; Timothy Flaharty settled in Boston Massachusetts in 1767; Ann Flaherty settled in New York in 1850.
