Probably a Welsh form of Eugene, though it might be derived from Welsh eoghunn meaning "youth". This was the name of several figures from Welsh history and mythology. In Arthurian legend Owain (also called Yvain in French sources) was one of the Knights of the Round Table, the son of King Urien and husband of the Lady of the Fountain. His character was based on that of Owain ap Urien, a 6th-century Welsh prince who fought against the Angles. This name was also borne by Owain Glyndwr, a 14th-century leader of Welsh resistance against English rule.
