Regan Family Genealogy & History

Discover the Global Legacy of the Regan Surname

The surname Regan, along with its variants such as O'Regan and Reagan, is an Anglicized form of the Irish Ó Riagáin or Ua Riagáin. This name has its roots in ancient Gaelic, where "ri" means "sovereign" or "king," and the suffix "-in" implies a diminutive, leading to interpretations like "the king's child" or "big king." Historically, the Regan name was associated with two distinct Irish families: one based in Meath and the other in Thomond, both of which played significant roles in Ireland's rich history.

In the medieval period, the O'Regans of Meath were part of the southern Ui Neill and among the four Tribes of Tara, wielding influence in regions like south Breagh and northern County Dublin. They were active in conflicts against the Danes, notably capturing the King of Dublin in the 11th century. The Thomond O'Regans were a Dalcassian family linked to Brian Boru, a legendary High King of Ireland. Following the Anglo-Norman invasion, many Regans were displaced, leading to the spread of the family name across Ireland and eventually beyond its borders.
