History & Origin

Ollen is a rare surname-style first name. Most read it as a spelling of Allen (from Breton Alan) or as a cousin of Scandinavian Olin. It has little documented history of its own, which makes it feel both familiar and unplaceable; the routes are uncertain, which we note (said 'OL-un').

In the U.S. it is very rare for boys. Rare, understated, and surname-style.
