Father of Kahedins and Isolde of the White Hands (Iseult) in Gottfried’s Tristan.
As the Duke of Arundel (Sussex), he was attacked by enemies, but was saved by Tristan. In return, he encouraged the marriage between Tristan and his daughter.
He appears in Eilhart’s Tristrant as the similar-sounding Havelin, and in later legend as Hoel.
