Madisson
Madisson is a variant spelling of the name Madison, which is derived from the English surname Madison. The surname itself is a patronymic name, meaning 'son of Maud' or 'son of Maddy'.
The name Maud is a medieval Germanic name derived from the Old German name 'Mahthildis', which is composed of the elements 'maht' meaning 'might' or 'strength' and 'hild' meaning 'battle'. Thus, the name Maud and its derivatives like Madison and Madisson originally carried the meaning of 'mighty in battle'.
Over time, the name Madison transitioned from being a surname to a given name, particularly popular for girls in the United States. The variant spelling Madisson is a more recent development, likely influenced by the trend of creating unique spellings of traditional names.
While Madisson does not have a distinct meaning separate from Madison, the name retains the connection to its Germanic roots and the idea of strength or might, albeit in a more subtle and modern form.
