History of the Murphy name

Murphy derives from the personal name Murchadh, meaning 'sea-warrior', and was borne by several unrelated septs. The largest were the Ui Murchadha of the Ui Cheinnsealaigh in south Leinster, kin to the medieval kings of Leinster and strong around Wexford, and a Muskerry sept in Cork under the overlordship of the MacCarthys. Smaller groups existed around Sligo and Roscommon. Because so many distinct families anglicised to the one form, Murphy became remarkably widespread rather than tied to a single stronghold, and by the 19th century had overtaken Kelly to become the most common surname in Ireland, a position it still holds, with its heaviest concentration in Cork and Wexford.
