Lewellyn

Lewellyn is a masculine name of Welsh origin, being a variant spelling of Llewellyn, which comes from the Welsh 'llyw' (leader) and 'eilun' (image, idol), essentially meaning 'leader's image' or 'lion-like.' This spelling variation simplifies the traditional Welsh double 'l' beginning, making it more accessible in English-speaking countries. Historically, Llewellyn was the name of several Welsh princes, including Llewellyn the Great who ruled in the 13th century. The Lewellyn variant maintains the name's distinguished heritage while offering a slightly more phonetic spelling. Though not among the most common names, Lewellyn appeals to parents seeking a name with Celtic roots and historical significance that still feels approachable and distinctive.

Lewellyn is also given to girls.

Pronounced loo-EL-in.
