Allin is in Origin.

Allin is an English given name and surname, a medieval spelling variant of Alan/Allan/Allen. The root is Breton Alan, brought to Britain by Norman-era Bretons, and it also overlaps with the Irish Gaelic Ailín, a diminutive of ail “rock,” yielding the often-cited meaning “little rock.” Because the Breton etymology is debated, some sources gloss the name more broadly as “handsome” or “cheerful.”

Medieval English records preserve Allin alongside Alan and Alen; parish registers from the 16th–17th centuries show Allin common both as a forename and a patronymic that became the surname Allin/Allins. The name’s prestige in England was boosted by Alan Rufus (Alan the Red), a powerful 11th‑century noble. Modern variants include Alan, Allan, Allen, and the Gaelic Ailín; related forms abroad are Alen (Slavic) and Alain (French). Short forms are Al and, occasionally, Ally. Usage today is uncommon but recognizably traditional.
