Arlyn, of Germanic origin, is a unisex given name that means 'eagle power'. It is derived from the Old Norse elements 'arl' meaning eagle and 'vin' meaning friend or follower.
"Arlyn saw its highest birth years between 1929 to 1947, with a peak of 66 births in 1939. However, from the 1950s onwards, its popularity significantly declined, with most years seeing fewer than 20 births. The name's usage has been quite inconsistent over time, with some years having no recorded births at all."
