Meaning & origin

Madoc is a rare Welsh name that has been used in the United States only since 2003, when it first appeared in Social Security records. Its peak year was 2016, after which it has been in decline, falling in popularity from 2017 onward. While Madoc has never reached the top 1000, its absence from the rankings reflects its status as an uncommon choice. The name carries legendary associations with the Welsh prince Madoc, said to have sailed to America in the 12th century, giving it a distinctive historical narrative. Parents drawn to Celtic heritage or unique names may find Madoc appealing, though its rarity means less than one in a million babies received the name in recent years.

Madoc is a name of Welsh origin, derived from the Old Welsh elements 'mad' meaning 'good' or 'fortunate'. It appears in medieval Welsh legend as the name of a prince who supposedly discovered America long before Columbus. The name has been used sporadically in Wales and among the Welsh diaspora, with modern usage reflecting a revival of interest in traditional Celtic names.
