Allison surname meaning

Allison is primarily an English and Scottish patronymic surname from Alison or Alice, with the ending marking descent or family association. Medieval records also allowed similar forms to develop from Allen, Ellis, Alexander, and related names, especially in Scottish contexts. Alison and Allyson are close spelling forms, while Allinson can make the son relationship explicit. Alice ultimately has a separate Germanic history, but that given-name etymology does not identify every Allison line. The catalog uses parent’s name for the main personal-name route, with disputed confidence because several overlapping medieval forms can produce the modern spelling.
