Probably an Irish form of LUGUS. In Irish mythology Lugh was a divine hero who led the Tuatha De Danann against the Fomorians who were led by his grandfather Balor. Lugh killed Balor by shooting a stone into his giant eye.
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).
