GUIGUES [IV] "Pinguis", son of GUIGUES [d'Albon] & his wife first wife Adelsindis --- ([1025/30]-19 Jan [1106], bur Priory of Saint-Robert). A charter dated to [1100] relates details of a dispute between the bishop and counts of Albon which names "Guigo Vetus, pater Guigonis Crassus…Guigoni comiti, filio Guigonis Crassis"[2683]. "Malleni episcopi Gratianopolitani et Wigonis comitis et uxoris eius Adelsendis, filiorumque suorum Umberti et Wigonis" signed a charter dated 26 Aug 1035 relating to the donation of four churches in Vico to the abbey of Saint-Chaffre[2684]. A charter dated 29 Apr 1050 records the donation by "Guigoni…maiori, qui postea effectus est monachus…et Adelai comitissæ, et alii Guigoni, filio illius Guigonis…et uxori eius Petronillæ" to Saint-Pierre de Vienne[2685]. "…Guigo comes et filius eius Guigo…" witnessed the charter dated 27 Jan 1052 which records an agreement between the archbishop of Vienne and the canons of the church of Romans[2686]. "Guigo comes qui nomine vocor senex atque filius meus Guigo pinguis" donated property to Oulx by charter dated 1063[2687].Comte d'Albon. "Wigo Albionis comes" named "fratres mei Guigonis cognomento Raimundi, Richardi, Armannique" in his donation to Cluny dated 1079[2688]. "Vuigo comes" donated property "in parrochia Heroneii" to Domène by undated charter[2689]. "Wigo…comes" confirmed a donation to Cluny by charter dated [1100][2690]. "Guigonis comitis, filii Guigonis Veteris…" subscribed the charter dated 22 Jan 1105 relating to a donation to the cathedral of Grenoble[2691]. Chorier´s Histoire de Dauphiné states that an epitaph in the priory of Saint-Robert records the death 19 Jan of "Guigo Grassus Dalphinus primus et monachus" but comments that it was erected long after his death[2692].
m (before 29 Apr 1050) PETRONILLE, daughter of --- ([1039/41]-9 Sep, before 1106, bur Priory of Domene). A charter dated 29 Apr 1050 records the donation by "Guigoni…maiori, qui postea effectus est monachus…et Adelai comitissæ, et alii Guigoni, filio illius Guigonis…et uxori eius Petronillæ" to Saint-Pierre de Vienne[2693]. According to Europäische Stammtafeln[2694], the first wife of Guigues [IV] was Adelaide de Savoie, daughter of Oddon Comte de Chablais, Marchese di Susa & his wife Adelaida Marchesa di Susa ([1052/53]-[Schloß Twiel] early 1079, bur St Blasius). Another table in Europäische Stammtafeln[2695] shows the first wife of Guigues Comte d'Albon as "Adelais (von Turin)" and their son Guigues [V] Comte d'Albon as co-heir of Adelaida Marchesa di Susa in 1091. The basis for this hypothesis has not been found, but it is unlikely to be correct considering Adelaide's estimated birth date. On the other hand, it is likely that the first wife of Guigues [IV] was a descendant of Adelaida Marchesa di Susa, assuming that it is correct that his son Guigues [V] was one of her co-heirs in 1091. If that is correct, it is possible that his wife was the daughter of Adelaida´s second marriage to Enrico di Monferrato, and therefore born in [1039/41]. If Guigues [IV]´s wife was Petronille named in the charter quoted above, she would have still been a child at the time of the marriage. The necrology of the priory of Saint-Robert records the death "V Id Sep" of "la comtesse Pétronille, épouse de Guigues le Gras et mère de Guigues le comte"[2696]. Her burial place is confirmed by the charter dated 1106 under which "dominus Vuigo comes et uxor eius Regina quæ fuit de Anglia" confirmed a donation to Domène which states that "matris suæ" was buried in the monastery[2697].
Guigues [IV] & his wife had [three] children
