Lleu

Probably a Welsh form of LUGUS. In the Mabinogion, 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.

LUGUS   male   Celtic Mythology
Probably from early Celtic meaning "light", ultimately from the Indo-European root *leuk "light, brightness". This was the name of a Celtic (Gaulish) god of commerce and craftsmanship, who was equated by the Romans with Mercury. He probably forms the basis for the characters and names of Lugh (Irish) and Lleu (Welsh).
