Research Notes:

A charter dated 1145 records that “Ansellus de Hosden et Aiglina uxor eius” donated property “qui leur apartenoit du chef de ladite dame au village de Courcelles le Comte” to Eaucourt abbey, Artois, with the consent of “Robert fils dudit Ansellus de Hosden et de Ingerannus comes Ternensis et de Anselm frère dudit Ingelrannus...Adelais seur de ladite Aiglina”.... ^2a

"Robertus…Betuniæ advocatus" donated "villam…Monciacum" {Monchy} to "abbate Nicolao et monachis Corbeiensibus", for the souls of "…uxoris Adelisæ et filiorum", by charter dated to [1140], signed by "Balduinus de Atrebato, eiusdem advocati cognatus". The last-named person in that document may provide a clue to Adelaide’s family origin, the term "cognatus" indicating frequently, although not exclusively, brother-in-law. “Clementiæ dominæ de Chokes, matri Roberti advocati de Bethunia” donated “terram…Mansus” to "abbas S. Johannis de Chokes", with the consent of "filio eius Roberto Betuniensi advocato et uxore eius Adelide et filiis eius Roberto, Baldewyno, Willermo et filia eius Clementia". "Robertus de Betunia, Atrebatensis advocatus…advocatus de Warneston et Adhelis uxor mea et filii mei Robertus, Willelmus, Balduinus" confirmed the possessions of Warneton abbey by charter dated 1177. The 13th century Histoire des ducs de Normandie et des rois d’Angleterre suggests that Adelaide may have been related to the family of the seigneurs de Saint-Valéry in Normandy when it names "fille fu Bernart de Saint-Waleri…Mehaus" as the wife of "Guillaumes de Brayouse" and comments that she once boasted about her cows to "Bauduin le conte d’Aubemalle son neveu". The precise relationship between Mathilde de Saint-Valéry and Adelaide’s son Baudouin has not been ascertained.

The necrology of Béthune Saint-Barthélemy records the death “V Id Sep” of “Aelidis advocatissa uxor Roberti Rufi”. ^2b
