Allisson is a modern respelling of Allison/Alison, a name rooted in the medieval French diminutive of Alice (Aalis/Alis), itself from the Old High German Adalheidis meaning “noble kind” or “of noble type.” The name also developed as a metronymic surname in Britain - “son of Alice” - before returning to first-name use. Its core meaning centers on noble lineage or character.

Alison was common in medieval England and Scotland, with Chaucer’s Alisoun cementing an early footprint. In the 20th century, Allison rose sharply in the Anglophone world. The double‑s spelling Allisson appears in Latin America and among Portuguese- and Spanish-speaking families, where ss signals a clear /s/ (cf. Portuguese Alisson).
