Welsh tradition remembers the queen's sister Gwenhwyfach and records the enmity between them. Two Triads ("", no. 53, 84) mention Gwenhwyfar's contention with her sister, which was believed to be the cause of the Battle of Camlann. In the mid-late 12th-century Welsh folktale "Culhwch and Olwen", she is also mentioned alongside Gwenhwyfach; in some later prose romances, she appears as Guinevere's evil twin. German romance "Diu Crône" gives Guinevere two other sisters: Gawain's love interest Flori and Queen Lenomie of Alexandria.
