Lleu

Probably a Welsh form of Lugus. In the Fourth Branch of the Mabinogi [1], Lleu Llaw Gyffes is the son of Arianrhod. He was raised by his uncle Gwydion, who helped him overcome the curses that his mother placed upon him. His wife Blodeuwedd and her lover Gronw conspired to overcome his near invincibility and murder him, but they were not successful. Eventually he became the king of Gwynedd.
