  Research Notes:

Her origin is confirmed by Malaterra who records the marriage of "comes Rogerus" and "Adelaydem…neptem Bonifacii…Italorum marchionis, filiam…fratris eius", dating the event to 1089. Albert of Aix records that she was "ortæ de sanguine Gallorum" and refers to her consanguinity with her second husband, but the precise relationship has not been traced. According to Houben, she was "barely 15" on her first marriage, although the basis for this statement is not known and if it is correct her assumed birth year would be earlier or later than [1072] depending on the actual year of the marriage.

She was regent of Sicily for her sons Count Simon and Count Roger II 1101-1112, jointly with Robert de Bourgogne, the husband of one of her step-daughters. She suppressed rebellions by her vassals with great severity. She established the Sicilian capital at Palermo [Mar/Jun] 1112. Fulcher of Chartres specifies that King Baudouin married the widow of Roger Count of Sicily and names her "Adelaidis" in a later passage. Albert of Aix records the marriage at Acre of King Baudouin to the widow of "Rotgeri ducis Siciliæ, fratris Boemundi", describing in detail the magnificence of her suite, dated to [1113] from the context. As a condition of her second marriage, she insisted that her son by her first marriage, Roger Count of Sicily, would become heir to Jerusalem if the second marriage produced no other heir. Albert of Aix records that Arnoul Patriarch of Jerusalem ordered the king to repudiate his wife "propter adulterium" in relation to his "prima conjuge, de orta de principibus Armeniæ", implying that the former wife was still alive when the king remarried, but adds that the king was also accused of consanguinity with his wife who was "ortæ de sanguine Gallorum", whereupon his wife returned to Sicily. A further difficulty was presumably the possibility of the crown of Jerusalem passing to the count of Sicily, in accordance with the arrangements made at the time of Baudouin´s third marriage, but this is not mentioned by Albert of Aix. Fulcher records her death in Sicily in April immediately after recording the death of King Baudouin.

The Annales Siculi record the death in 1118 of "Adelasia regina Ierosolimitana mater regis Rogerii". ¹
