Llewellyn

Llewellyn is a Welsh name used as both a given name and a surname. It derives from the medieval Welsh name Llywelyn, which was borne by Welsh rulers such as Llywelyn the Great (Llywelyn ab Iorwerth) and his successors, who played a central role in the history of Gwynedd and Wales.

The name spread in Wales and among Welsh communities abroad, with common spellings including Llewellyn, Llewelyn, Llywelyn, and Llywellyn. In modern times it is used across generations and appears in various public figures, literature, and media.

In addition to people, Llewellyn is used in organizational names. Llewellyn Publications, later Llewellyn Worldwide, is a U.S.-based publisher of occult, metaphysical, and New Age books.

The name remains part of Welsh cultural heritage and continues to be used around the world, reflecting its historical roots and enduring presence in both personal names and cultural references.
