  • Kate O'Riordan says:

    My father – born 1910 – used to say that Foley (his mother’s family name) meant “robber or plunderer” – as you have it – BUT he held that it would therefore have been a Viking or Norse name. He was born in West/Mid Cork and had a few references to Vikings in his normal speech (English). On a very cold day, for example, he would say: “it would skin the Danes”.

  • Joseph Fitzhenry says:

    Meiler Fitzhenry Great Grandson of William I of England (William the Conqueror, William of Normandy), Grandson of Henry I, and cousin or brother of several other famous Normans and who entered Ireland with Robert FitzStephen in 1169 He returned in 1173 with Richard de Clare (Strongbow) throwing Ireland into revolt. He was granted huge estates throughout Ireland including Offaly, Carbury, Kildare, Limerick and later Leix. Eventually were added estates in Kerry and Cork. He was Lord Chief Justice of Ireland for many years, and founded the monastery of Great Connell Priory in Kildare.
    With such prominence of effect on the formation of modern Ireland post the English invasion, I was wondering how an Irish name such as Fitzhenry (Fitzhenry) does not appear on a list of Irish surnames?

  • Adrian Foran says:

    FORAN is the Anglicized form of the Gaelic (Irish) name ‘O’Fuarthain, O’Fuarain’, meaning ‘descendant of Fuar(th)an’, a personal name believed to be derived from the Gaelic ‘fuar’, cold. The name was first Anglicized as O’Forhane and Forahan, these forms being used mostly in County Kerry and West Cork. The first recorded spelling of the family name is shown to be that of O Foirtchern, which was dated 1175, Annals of the Four Masters, during the reign of Rory O’Connor, High King of Ireland, 1166-1175. Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to “develop” often leading to astonishing variants of the original spelling.

  • Bob says:

    The surname Ó Oireachtaigh, is always found as MagOireachtaigh which means  “of the assembly or committie. I have never came across the O’ version in old manuscripts? The Mag is just Mac ‘son of’ but because of Mac  in the Irish language preceeding a vowel the C becomes a G.
