Alan traces its lineage to medieval Brittany, where a Breton term meaning either “handsome” or “little rock” quietly hitched a ride with the Normans and took root in the British Isles. From there it crossed the Atlantic, enjoying its American heyday amid the baby-boom years—peaking inside the national top 50 during the 1950s—before settling into today’s steadier middle ranks. Historical and pop-culture carriers such as code-breaking pioneer Alan Turing, lunar-minded astronaut Alan Shepard, and the wry actor Alan Alda have furnished the name with an air of understated intellect and pragmatic daring. Cleanly pronounced AL-ən, it asks little of the tongue and even less of the spelling bee, yet its cousins Allan and Allen lurk nearby for parents who crave extra consonants. In short, Alan is a compact, time-tested choice: familiar without feeling overplayed, quietly confident without shouting for attention.
