; Raoul repudiated his wife, Eleonore, in order to marry Petronille. With the complaints of several bishops, the Pope excommunicates both Petronille and Raoul I on the pretext of consanguinity, and a Council in Lagny would condemn the prelates who assisted Raoul. King Louis VII de France takes strong exception to this action, and has his brother Robert de Dreux invade Champagne. The Pope promisses to lift the excommunication, but in 1143, Innocent II, would recant his promise and Louis VII would burn the town of Vitry which would then be renamed to Vitry-le-Brule. When Innocent II died on 23 September 1143, His successor Celestin II would lift the interdict and validate the marriage of Raoul I and Petronille.¹²

Orderic Vitalis records that in 1096 "Hugo Crispeii comes" placed "Radulfo et Henrico filiis suis" in charge of his land, married "Ysabel filiam suam" to "Rodberto de Mellento comiti", and left on pilgrimage taking "secum nobile agmen Francorum"[340].

He lost an eye at the siege of the château of Livry in early 1129. Louis VI King of France appointed him seneschal of France in Nov 1131.

His repudiation of his first wife triggered war with Champagne and excommunication by the Pope, although the divorce was finally accepted by the church in 1148. Robert of Torigny records the death in 1152 of "Radulfus de Perrona comes Viromandorum", specifying that he appointed "Galeranni comitis Mellenti nepotis sui" as guardian of his infant children[344].

     III. Wikipédia (FR) - Liste des seigneurs de Montpellier offers the following (dates are for reigns, not necessarily birth and death, though the end of a reign usually coincided with an individual's death)
III.1 Guilhem I de Montpellier 985 - ca 1025
III.2. Bérenger/Bernard de Montpellier
-->III.2. Guilhem II de Montpellier, ca 1025 - ca 1059, nephew of the Guilhem I, son of Bérenger (or Bernard) de Montpellier
-->III.3.1 Guilhem III de Montpellier, ca 1059 - ca 1068, son of the Guilhem II
-->III.3.2 Bernard Guilhem IV de Montpellier, ca 1068 - 1085, brother of Guilhem III
-->III.4 Guilhem V de Montpellier,1085 - 1122, son of Guilhem IV


     IV. H&T offer an extensive and well-documented analysis of the verious hypotheses regarding this line and conclude that the most commonly espoused hypothesis shows (see attached image of the diagram from the H&T website):
Siblings:
IV.1.1 Berenger
IV.1.2 Guilhem I [Bernard] de Montpellier m. Chimberge
IV.1.3 Trudgarde b. 960 d. bef 1022 m. Bernard (it is unclear whether Trudgarde or Bernard was the sibling of the other two)
-->IV.2 Guilhem II Bernard m. Beliarde (H&T state: "Guilhem I n’ayant probablement pas eu d’enfant adopte celui de Tudgarde, le fameux Guilhem II Bernard." (Guillem I probably not having children, adopted that of Trudgard, the famous Gillhem II Bernard." [translation by GA Vaut]
-->IV.3 Guilhem III Bernard m. Ermengarde de Narbonne
-->IV.4 Guilhem IV b. 1073 d. 1122 m. Ermessinde


Conclusion: I tend to be swayed by the arguments of Settipani and therefore have adopted the lineage as outlined by Genealogics for Guillem/Guillaume IV and V (father/son). This leaves unanswered the question of whether Guillem/Guillaume II was the son of Guillem/Guillaume I (per Genealogics) or of one of his siblings, Bernard/Berenger (per Med Lands) or Trugarde & Bernard (per H&T). Med Lands, Wikipédia (FR), and H&T disagree with the Genealogics descent, showing Guillaume/Guilhem/Guillem II not as the son of Guillaume/Guilhem/Guillem I, but rather of his sibling, named variously Bernard, Berenger or Bernard/Berenger. For now, I have also adopted H&T's lineage, but continue to search for other information. GA Vaut.^{10,11,12,9,13} He was living in 1058.⁶ He was Seigneur de Montpellier between 1068 and 1085.^2,12
