Pronunciation: oh REER-dun; Irish Ó Ríordáin: oh REER-dawn

History of the O'Riordan name

Ó Ríordáin is a contraction of Ó Ríoghbhardáin, from ríoghbhard, 'royal bard'. The sept arose in the Ely O'Carroll territory of north Tipperary and Offaly, but was driven south-west by the Anglo-Norman advance in the 13th century and re-rooted itself in Co. Cork, especially in the Muskerry country along the Lee valley, where the name has been thick ever since; Limerick and Kerry also have many. The spellings O'Riordan, Riordan and Reardon all represent the same name. Its modern bearers span the two languages of Ireland: Seán Ó Ríordáin remade poetry in Irish in the 20th century, while Dolores O'Riordan of Limerick carried the name around the world with The Cranberries.
