The family name Regan, along with its cognates O'Regan, O Regan, Reagan, and O'Reagan, is an Anglicized form of the Irish surname Ó Riagáin or Ó Ríogáin, from Ua Riagáin. The meaning is likely to have originated in ancient Gaelic ri "sovereign, king" and the diminutive suffix -in; thus "the king's child" or "big king".[4] The name was borne by two distinct families: one seated in Meath, the other in Thomond.[citation needed]
The O'Regans of Meath were a branch of the southern Ui Neill and one of the four Tribes of Tara. Before the Anglo-Norman invasion, they were lords of south Breagh and the north of present-day County Dublin. They took a leading part in the wars against the Danes. In the year 1029, Mathghamhain Ó Riagáin, king of Breagh, captured the king of Dublin, Amhlaoibh son of Sitric, releasing him only upon payment of an enormous ransom, which included the celebrated Sword of Carlus. The O'Regans were dispossessed soon after the invasion and dispersed through Ireland.[5]
The O'Regans of Thomond are a Dalcassian family said to be descended from Riagán, son of Donncuan, a brother of Brian Boru.[6]
The unisex forename Regan is likely to have derived sometime later from the Latin Regina "queen", the feminine form of Rex (stem reg-) "king", which is also the source of the name Reginald.[2]
