Meaning & Origin
Madisson is a girl's baby name of Old English origin, an alternate spelling of Madison, from the surname meaning 'son of Maud' or 'son of Matthew,' derived from the medieval name Maud (a form of Matilda, meaning 'mighty in battle').
The double-s spelling is a distinctive variant that sets this form apart visually from the standard Madison. Still carrying all the associations of the popular Madison — including the 1984 movie Splash that launched the name — Madisson simply presents it with a more elaborate written form.
