Modern invented name, possibly derived from Maddox
Madex is a contemporary American invention, likely created as a stylistic variation of the Welsh name Maddox or the English surname Maddux. It follows the popular trend of using the 'x' ending to create a sharp, energetic sound. While it lacks a deep historical etymology, it is often associated with the meaning 'son of Madoc' or 'fortunate' by extension of its phonetic roots.
Fewer than 5 boys were named Madex in 2025.
