Show ContentsCarthy History, Family Crest & Coats of Arms

The many Irish surnames in use today have long rich histories behind them. The name Carthy originally appeared in Gaelic as Mac Carthaigh, which is derived from the word "carthach," which means "loving."

Saint Carthach the Elder (d. 580?), appears in "the 'Felire' of Engus the Culdee (10th cent.) with the epithets of royal and Roman attached to his name. This is generally interpreted to mean that he was of royal ancestry, and had travelled to Rome [cf. Cainnech, Saint]. From the 'Vita Kierani' (Bollandist A. SS., March, v. 395) we gather that he was the grandson of Angus, king of Munster, who would seem to be the king whose death is recorded in the 'Four Masters' under the year 489. Colgan, however, noting that he was the brother of St. Cuanna, quotes from an old genealogy to show that he was the great-grandson of Neill of the Nine Hostages, who died about the year 405. In the 'Vita Kierani,' St. Carthach appears, before the death of St. Patrick, as one of St. Ciaran of Saighir's young disciples." 1

Saint Cathach the Younger (d. 636) also called Mochuda, was "the founder of the famous monastery at Rahen, and bishop of Lismore, was the son of Finnall (Annals Four Masters, sub an. 631). According to his legendary life, which, however, seems to have preserved much that is historical, he was born in Kerry, of the race of Fergus." 1

Early Origins of the Carthy family

The surname Carthy was first found in County Kerry and much of County Cork, in the area formerly known as Desmond. One of the oldest and most important of all Irish families, the MacCarthy family claim descent from Oilioll Olum, the 3rd century King of Munster who gave the region of Desmond to his son Eoghan after his death. Eoghan's descendants were known as the Eoghanacht, and the surname MacCarthy is derived from Carthach, an 11th century lord of this group who was killed when the Lonegans set his house on fire.

They were settled at Carrignavar where they were the Lords of Eoghannacht and Diarmod MacCarty Mor swore fealty to King Henry II thereby retaining his estates in Cork. Innumerable members of the family have been important in Irish history, especially those with the forenames Fineen, Florence or Justin, beginning with the Fineen MacCarthy who vanquished the Geraldines in 1261.

Several branches of the powerful MacCarthy sept existed, including MacCarthy Reagh, who held a family seat at Carbery in West Cork, and the Muskerry MacCarthys, who were based in the barony of Muskerry in that county. MacCarthy Mor of County Kerry, long thought to be extinct, has only recently been proven to still exist.

The McCarthy Reagh branch rose to become the Princes of Carbery in what is now southwestern County Cork in the 13th century. It is generally thought that Donal Reagh MacCarthy, the 5th Prince of Carbery, a quo MacCarthy Reagh, son of Donal Glas was the first to use Reagh is his surname. From this early listing, each subsequent prince continued to use Reagh in one form or another. As far as the early princes are concerned, we know very little. However from Finghin MacCarthy Reagh, the 8th Prince of Carbery from 1477 to his death in 1505, a solid genealogy has been determined.

The Carthy Motto +

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.

Motto: Forti et fideli nihil difficile
Motto Translation: Nothing is difficult to the brave and the faithful
