Adelaide ....

m firstly ( [1120/23] ) ADELAIDE, daughter of --- (-after Jul 1134). "Comes Amedeus…cum uxore sua Adeleida comitissa" confirmed the rights of the monastery of "S. Justi in villa Volveria" by charter dated 27 Jul 1134, witnessed by "Umbertus de Bocsosello, Aimo de Brianzone…"[193]. Europäische Stammtafeln shows the single marriage of Comte Amedée III, to Mathilde d'Albon, in 1123[194]. Given the likely birth dates of Alix de Savoie, oldest daughter of Comte Amedée, and of Mathilde d'Albon (see below), it is unlikely that Mathilde was the mother of Alix. A first marriage of Comte Amedée is therefore highly probable. Palluel shows Comte Amedée III's first wife as Gertrude de Lorraine, daughter of Simon I Duke of Lorraine[195]. This can be dismissed as incorrect. Neither Europäische Stammtafeln[196] nor Poull[197] refers to any such daughter of Duke Simon. In addition, bearing in mind that Duke Simon himself was probably born in 1096[198], it is chronologically impossible for any daughter of his to have given birth to a child in [1123/25]. Her marriage date is estimated based on the estimated birth date of the couple's supposed elder daughter, Alix de Savoie, as shown below. The origin of Adelaide is unknown. However, according to Europäische Stammtafeln, her supposed daughter Alix was Dame de Châteauneuf-en-Valromey, de Virieu-le-Grand, et de Cordon-en-Bugey[199]. Further research to trace the ownership of these fiefdoms may provide clues about the origin of Adelaide.
