Surname O'Reardan - Meaning and Origin

all surnames with 'O'

O'Reardan: What does the surname O'Reardan mean?

The Irish surname O'Reardan (or its variants O'Riordan/O'Riordain) is derived from the Gaelic "ó Rodáin”. This phrase translates to "descendant of Riordain", "Riordain" being an ancient Irish personal name from a Celtic root word meaning "high" or "noble". It is believed that the name originated with a single progenitor, Riordain himself, during the Middle Ages in Ireland.

The O'Reardans were one of the many Irish clans associated with the ancient kingdoms of Munster and Leinster. It is believed that they were descended from one of the many branches of the powerful and respected O'Neill dynasty of Ulster. O'Neill was the royal name of the ruling clan of Ulster since the 10th century C.E.

Since the clan's origins in the Middle Ages, the O'Reardans have been part of Ireland's varied history, participating in her battles and struggles such as the 1798 Rebellion against the English. They were also some of the many Irish families forced into exile when the country suffered from the Great Famine during the mid 1800s.

Today, the O'Reardans are still found scattered throughout Ireland, with others who have immigrated to other parts of the world. They are a proud family dedicated to the preservation of their heritage and the history of the O'Neill dynasty in old Ireland.
