Commentary
Cawley: "According to Europäische Stammtafeln, 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 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 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 that marriage."
