What does Callen mean, and where does it come from?
Callen anglicises the Irish surname Ó Cathaláin, from cathal — "battle-mighty" — and doubles as a variant spelling of Callan, a town in County Kilkenny. It is a recent arrival as a first name: recorded in small numbers from the 1950s, it entered the US top thousand in 2010 and has held a steady place since, carried along by the same taste for two-syllable -en endings that lifted Callum, Camden and Holden. The double L gives it a softer opening than Callan, and Cal comes ready-made as the everyday form.
