Meaning & Origin
Madox is a boy's baby name of Welsh origin, a variant of Maddox, from the Welsh Madoc or Matoc meaning 'fortunate' or 'good' — possibly from the Old Welsh mad (good, lucky) — a name of positive aspiration with deep Celtic roots.
Madox carries the same Welsh heritage as the more common Maddox, worn most famously by Angelina Jolie and Brad Pitt's eldest son, who helped launch the name to wider attention. The single-d spelling gives it a cleaner, more streamlined look that some parents prefer for its visual simplicity.
