Meaning & origin

Madox first entered U.S. birth records in 2004, a relatively recent addition to the pool of given names. Its peak popularity came in 2009, after which it has seen a steady decline. Today, the name is rare, with only about 1 in 284,679 newborns receiving it annually. The name's Welsh roots tie it to the ancient name Madoc, meaning 'fortunate,' though the modern spelling Madox is often seen as a variant of the more familiar Maddox. Despite its low rank, Madox carries a strong, surname-like quality that fits contemporary naming trends favoring short, distinctive names with an 'x' ending.

Madox is a patronymic surname derived from the Welsh personal name Madoc, which itself evolved from the Old Welsh 'Madawc' meaning 'fortunate' or 'goodly.' The name was historically used in Wales and later spread to England. As a given name, Madox gained modern attention in the early 2000s, partly due to celebrity use.
