History of the O'Callaghan name
The O'Callaghans take their name from Ceallachán Caisil, the 10th-century Eóganacht king of Munster celebrated in the saga Caithréim Cheallacháin Chaisil. The sept's territory, Pobal Uí Cheallacháin, lay along the Blackwater around Clonmeen in north Cork, where they were lords until the Cromwellian confiscations transplanted the chief line to east Clare, a move remembered in the placename O'Callaghan's Mills. A branch settled in Spain, where the family earned noble rank in exile. The name remains one of Cork's most characteristic, and a recognised chief of the name, The O'Callaghan, continued into modern times. Bearers have excelled in athletics, broadcasting and revolutionary politics.
