Galahad

From earlier Galaad, likely derived from the Old French form of the biblical place name Gilead. In Arthurian legend Sir Galahad was the son of Lancelot and Elaine. He was the most pure of the Knights of the Round Table, and he was the only one to succeed in finding the Holy Grail. He first appears in the 13th-century French Lancelot-Grail Cycle.
