Meaning & origin

Dylon is a modern respelling of the classic Welsh name Dylan, which derives from the mythology of the sea god Dylan. The variant spelling Dylon first appeared in US records in 1973, and peaked in popularity in 1992. Since 1993, its usage has been steadily declining, reflecting a broader trend away from respelled versions of traditional names. While less common than the standard Dylan, Dylon remains a recognizable alternative, appealing to parents who favor a distinctive spelling but want a name with deep cultural roots.

Dylon is a variant spelling of Dylan, a Welsh name from the elements 'dy' (great) and 'llanw' (sea, flood). In Welsh mythology, Dylan was a god of the sea. The name gained widespread use after the poet Dylan Thomas, though the Dylon spelling is a modern respelling, possibly influenced by the surname Dillon or commercial brands.
