Hugh
Hue and his brother, Sir Edward of the Red Castle, extorted a barony from the Lady of the Rock. Sir Marhaus (or Yvain) championed the lady, fought the two brothers at the same time – as they had insisted – killed Edward, and ordered Hue to return the Lady’s lands and sent him to Arthur’s court.
Malory seems to say nothing more about Hue, but if he followed the usual pattern he probably reformed and became a companion of the Round Table.
