FLOREE
According to the Vulgate, she was the daughter of King Alain of Escavalon and the mother of Gawaine's oldest son, Guinglain. Vulgate VII seems to describe the encounter: after Gawaine rescued her, Floree came to his bed somewhat in manner of Sir Bercilak's lady in Sir Gawaine and the Green Knight. Since Floree meant it, it went farther, and Guinglain apparently resulted from this adventure. I do not know for sure whether Gawaine married Floree or not, but according to The Wedding of Sir Gawaine and Dame Ragnell he was married several times.
Malory does not name Floree, but in XIX, he calls Sir Brandiles' sister the mother of Gawaine's sons Florence and Lovel. Although Malory does not name Brandiles' sister as the mother of Gawaine's son Gingalin, who surely is identical with the Vulgate's Guinglain, the name of the second son, Florence, is so similar to the name Floree that it strongly suggests a mother-son connection. Floree, then, might be identified with Sir Brandiles' sister.
