Daughter of William de Vernon (de Reviers/Redvers), Earl of Devon (d 1217) and Mabile de Meulan (d/o Robert de Beaumont Ct of Meulan and Matilda of Cornwall):

JOAN de Vernon (-after 1233). The Fundationis et Fundatorum Historia of Forde Abbey names “Johannam…Willielmi Brewer et Mariam Roberti de Courtney…uxores” as the two daughters of ”Willielmum de Vernona” & his wife, adding that Joan was childless[510]. "Hubertus Camarerius" paid a fine for his agreement with "com Devon de maritanda sui Joha fil ipsius comitis", dated 1200[511]. A charter dated 28 Apr 1200 confirmed the marriage contract between "Willm de Vernon comes Devon…Johe filie ipsius comitis junioris" and "Hub de Burgo dni Regis camerarium", confirming that "honoris sui in Devon cum castello de Plinton" had been allocated to "filie sue priori natu" while "insula de Wicth et Cristeschirche" were assigned to the younger daughter[512]. This document confirms that Joan was the younger daughter, despite the order in which the daughters are named in the Fundationis, and also that the division of property was made before the birth of their brother Baldwin in the absence of a male heir. The Testa de Nevill includes a list of fees of William Briwere, dated 1234, which names "Johanne que fuit uxor predicti Willelmi Briwere"[513].
