Curt Hofemann, curt_hofemann@@yahoo.com, posted the following, which indicated a source which recently suggested that the mother of Isabelle was not Lucienne, 1st wife of Louis VI, but a Marie de Breuillet. I have not seen any further discussion of this within the Gen-Medieval newgroup, so I think it is too early to say:
ES II:11 indicates b. (1088)=circa 1088, father: Guichard III
Research note 1: According to the current edtion, LES CAPETIENS, by van Kerrebrouck, p 83, the mother of Isabelle, dtr of Louis VI, is Marie de Breuillet, dtr of Renaud de Breuillet. [Ref: Robert S Baxter <rsbaxter@@bellsouth.net> message to Gen-Medieval 21 Apr 2002]
Research note 2: mother: Adelaide de Crecy
Research note 3: mother: Elise de Corbeil
ES II:11, ES XI:156 = m1 1104 Louis VI 'le Gros' K of F. Divorced (annulled) 1107.
Louis VI was engaged to Lucienne de Rochefort [the same as de Montlhery], but the marriage was not consummated and was annulled on grounds of consanguinity by the council of Troyes presided over by Pope Pascal II. [Ref: Robert S Baxter <rsbaxter@@bellsouth.net> message to Gen-Medieval 21 Apr 2002 citing: LES CAPETIENS, p 79 et seq, by van Kerrebrouck]. Research note: who was the common ancestor of Lucienne and Louis? Also, was dau Isabelle legitimated when they married then again made illegimate upon annullment?
m2 nach (after) 23.V 1107 [Ref: ES III:624, ES XI:156] um (about) 1107 [Ref: ES II:11] to Guichard.
d. nach (after) 1137 [Ref: ES III:624]
