Beatrix DE FAUCIGNY
"Willelmus…Gebennensis comes" founded the Chartreuse monstery of Pommiers, with the consent of "Humbertus filius meus…B. quoque uxor mea et filius meus Aymo quinquennis", by charter dated 1179. Her parentage is confirmed by the Chronicle of Alberic de Trois-Fontaines which names her daughter "Margareta filia domni de Fusceneis de matre Guilelmi, filii Humberti comitis Gebenensis" as wife of "comitis Thome de Sabaudia".
Beatrix married Guillaume I DE GENÈVE Count of Geneva, son of Amedeé I DE GENÈVE Count of Geneva and Mathilde DE CUISEAUX, after 1177. (Guillaume I DE GENÈVE Count of Geneva was born between 1131 and 1137 in Geneva, Switzerland and died on 25 Jul 1196.)
