Legend In Geoffrey of Monmouth's Historia Regum Britanniae, Igerna enters the story as the wife of Gorlois, Duke of Cornwall. In Thomas Malory's Le Morte d'Arthur, her daughters by Gorlois are Elaine, Morgause and Morgan le Fay. In other works, the names, roles and even number of Arthur's half-sisters vary depending on the text (including none in the Historia, in which Arthur has only a younger sister). In the Brut Tysilio, Cador of Cornwall is their son. John Hardyng's Chronicle calls Cador Arthur's brother "of his mother's syde".
