Meaning & origin
Lewellyn is a rare Welsh name that peaked in the United States in 1929, reaching its highest rank on record. Despite having over a century of recorded usage since 1912, it has never entered the top 1000 and remains a distinctive choice. The name's trajectory has been stable, suggesting consistent but infrequent use. While its exact meaning is uncertain, it is firmly rooted in Welsh history and shares heritage with the more common spelling Llewellyn, a name associated with medieval princes and enduring Welsh identity.
Lewellyn is a variant spelling of Llewellyn, a name derived from the Welsh elements 'llyw' (leader) and 'eilyn' (like), or possibly from 'llew' (lion) and 'gelyn' (enemy). Historically, it was borne by several medieval Welsh princes, notably Llywelyn the Great. The name has been used in Wales for centuries and spread to English-speaking countries through Welsh immigration and literary influence.
