History & Origin

Rhegan is a modern respelling of Regan, which comes from the Irish surname O Riagain, usually connected to ri, 'king'. In literature the name belongs to one of King Lear's daughters, and in film to the possessed child in The Exorcist — associations families may or may not care about, but which we note honestly and without editorialising. The Rh- spelling gives it a Welsh-looking twist (said 'REE-gun').

It appears only rarely in the U.S. Rare, Irish-rooted, and modern in spelling.

Did you know? Regan is one of King Lear's daughters in Shakespeare, and also the child in The Exorcist — two very different reasons the name is remembered. We note both neutrally so families know what they are choosing.
