Percival

From Old French Perceval, name of a knight in a twelfth century Arthurian romance by the French poet Chrétien de Troyes. Shaped like Old French perce (“pierce”) + val (“valley”), but probably representing some Gaulish or Old Welsh name, possibly related to Welsh Peredur, from ber (“spear, lance”), from Proto-Celtic *beru (“spit”) + dur (“hard metal, steel”). Cognate with German Parzival and Parsifal.
