Annales Cambriae, but he was not portrayed as a traitor until the chronicles of the 12th-century Geoffrey of Monmouth. While Arthur is away he seduces his wife

Morgan 1 m & f Welsh, English, FrenchFrom the Old Welsh masculine name
Morcant, which was possibly derived from Welsh

Morgan 2 f Arthurian CycleModern form of
Morgen, which was used by Geoffrey of Monmouth in the 12th century for the Arthurian sorceress Morgan le Fay, who was unnamed in earlier stories. Geoffrey probably did not derive it from the Welsh masculine name
