Allisoun is English, Norman French in Origin.

Allisoun is a medieval English form of Alison/Alisoun, ultimately rooted in Old French Aalis/Aaliz (Alice), itself a shortened form of Adelais from the Germanic Adalheidis. The components adal “noble” and heid “kind, type” give the name the sense “of noble sort.” Carried to Britain after 1066, it flourished in 13th–15th-century England and Scotland as a familiar pet form of Alice, created with the French -on/-oun diminutive. Middle English spellings varied widely; Chaucer’s works preserve forms such as Alisoun, giving the name a distinctly literary medieval aura.

Modern variants include Alison, Allison, Alyson, Alisoun, and the rarer Alizon; related forms are Alice and Aline. Short forms include Allie, Ally, and Lis. Allison also developed as a Scottish surname. While the double-l Allisoun is archaic, it appeals to those seeking a historically grounded yet distinctive twist on a classic “noble” name.
