Welsh unisex name GWYN means "fair, holy, white." In mythology this is a masculine name. In Welsh mythology, it is the name of the ruler of the underworld (Annwn) where he escorted the souls of the dead. In Arthurian legend, Gwyn ap Nudd ("fair/white son of Nudd") was the abductor of the maiden Creiddylad after her elopement with Gwythr ap Greidawl, a long-time rival of his. He helped Culhwch hunt the boar Twrch Trwyth, and in later legends he was king of the "fair folk" (tylwyth teg).
