The sister of King Agloans of Escoce.
Her lover was killed by Lord Girflet during a Sparrowhawk tournament in the city of Becleus. Margerie fled from the city and ran into Guinglain (Gawain’s son), who listened to her story and promised to help her.
Together, they returned to Becleus, where Guinglain defeated Girflet and properly awarded the sparrowhawk to Margerie. Margerie returned to Escoce under the protection of a knight Girflet provided.
