15 Last Names That Reveal Hidden Irish Ancestry — Is Yours On The List?

Most Irish Americans know they are Irish. Very few of them know what that means at the level of the name itself — what the name meant before it was anglicized, what it meant in the original Irish, what the person who first carried it actually was. Because the name your family carries today is not the name they left Ireland with. The O was dropped. The Mac was removed. The Gaelic form was traded for something simpler before it ever reached American soil. And behind every one of these fifteen surnames is a story that the American version of the name has never told you. Murphy — from Ó Murchadha — means sea warrior. The most common surname in Ireland traces to the Irish raiders who sailed against the British coast before the Viking Age. Kelly — from Ó Ceallaigh — has been debated for centuries. Bright-headed. Warlike. The first recorded Ceallach was a chief of a western Irish kingdom documented in the year 874. Sullivan — from Ó Súilleabháin — means dark-eyed. In 1890 approximately ninety percent of all O'Sullivans were in Munster. The O was dropped in America when Irish families calculated the cost of an obviously Irish name in a market where No Irish Need Apply signs appeared in newspaper ads and shop windows from the 1840s through the early 20th century. Walsh — the fourth most common surname in Ireland — does not come from the Irish language at all. Walsh comes from the Irish word Breathnach meaning Briton or Welshman — the name given to the Welsh soldiers who came to Ireland with Strongbow's Norman invasion in 1170. They became so thoroughly Irish that Walsh is now one of the most Irish names in existence. Most common in County Mayo. Carried by millions of Irish Americans who have never been told their name means foreigner. Byrne comes from Ó Broin — descendant of Bran, meaning raven. The raven was one of the most powerful symbols in Celtic mythology, associated with battle and prophecy. The historic Byrne family were lords of County Wicklow, notable for fierce resistance to outside invaders for centuries. Ryan comes from Ó Riain — little king — so ancient that its exact meaning has been obscured by time. The Ó Riains were chiefs in Counties Carlow and Wexford. Doyle comes from Ó Dubhghaill — dark-haired foreigner — the specific term the Irish gave to the Danish Vikings who settled their coastlines in the 9th century. If your name is Doyle your Irish ancestors were themselves descended from Danish Vikings who built Irish cities and became Irish over generations. Kennedy comes from Ó Ceannéidigh — helmeted head or fierce head — the name of the family whose most famous American descendant came from County Wexford. Fitzgerald comes from the Norman French fils de Gerald — son of Gerald — a Norman family that arrived in Ireland in 1169 and became so Irish they were described as more Irish than the Irish. Burke comes from the Norman de Búrca — of the fortress — another Norman name that became one of the most Irish names in existence after eight centuries of Irish residency and intermarriage. Collins from Ó Coileáin means young warrior or cub — concentrated in County Cork and County Limerick. Flynn from Ó Floinn means red or scarlet. Carroll from Ó Cearbhaill means fierce in battle — tracing to an 11th century King of Ely. Brennan from Ó Braonáin means a teardrop or drop of moisture. Gallagher from Ó Gallchobhair is one of the great Ulster families of County Donegal.
