History & Origin

Keagen is a spelling of Keegan, from the Irish surname Mac Aodhagáin, 'son of Aodhagán' — a pet form of Aodh, 'fire'. Carried into first-name use, it reads bright and lively. This spelling is a recent American touch (said 'KEE-gun').

It appears only rarely for boys in the U.S., well behind Keegan. Rare spelling, Irish root.

Did you know? Behind Keegan stands Aodh, the old Irish name meaning 'fire' and once borne by a god of the sun. The little-diminutive gives the sense 'little fiery one', which we note.
