Meaning & origin
Maddyx is a modern respelling of Maddox that first appeared in U.S. birth records in 2005. It reached its peak rank of 9,457th in 2016, during the height of the 'Maddox' spelling's popularity. Since 2017, its usage has been falling. The name is given to both boys and girls, with an estimated 1 in 160,727 newborns receiving it in 2025. Its distinctive 'y' sets it apart from the original Welsh surname-derived Maddox, reflecting a broader trend of creative spellings in contemporary American naming.
Maddyx is a modern variant of Maddox, which originated as a Welsh patronymic surname meaning 'son of Madoc'. Madoc is a Welsh name meaning 'fortunate' or 'good'. The spelling with 'y' instead of 'o' is a contemporary styling, part of a trend of replacing vowels with 'y' for a unique look.
