Not true about Allison.

Actually, Allison has two origins.
One is etymologically feminine, of French origin. Alice --> Alicen (French diminuitive) --> Alison (Scottish spelling of Alicen after Norman invasion of Britain). The spelling Allison is a variant.
One is etymologically masculine, of Anglo-Saxon origin. Allison means "son of Al" (or probably other Al- names) or "son of Alice."
