Top 12 Most Irish Surnames EVER

The Irish usually have very distinctive surnames. Almost all Irish surnames are recognisable as being from the Emerald Isle as soon as you hear them. This article is a countdown of the most stereotypical Irish names that you’ll hear.

12. O’Connor  (ó Conchobhair)

Irish (Derry, Connacht, Munster): Anglicized form of Gaelic Ó Conchobhair ‘descendant of Conchobhar’, a personal name which is said to have begun as Cú Chobhair, from cú ‘hound’ (genitive con) + cobhar ‘desiring’, i.e. ‘hound of desire’. Present-day bearers of the surname claim descent from a 10th-century king of Connacht of this name. In Irish legend, Conchobhar was a king of Ulster who lived at around the time of Christ and who adopted the youthful Cú Chulainn.
