Adelvia ‘Helvide’ de Courtenay

Not the daughter of Reginald I de Courtenay, 1st lord of Sutton

From Peter Stewart, post at SGM, 27 January 2003 < GoogleGroups > “Parents of Elisabeth de Courtenay”

The following account of the first Courtenay family's last generations was given, largely from earlier secondary sources, in _Histoire généalogique et chronologique de la Maison royale de France..._ by Père Anselme (Pierre de Guibours) & others, third edition, 9 vols (Paris, 1726-33), vol I pp 474 and 527-8:

• 1 Miles, seigneur de Courtenay, died after 1127 [NB actually in or after 1138 when he last occurs], married ca 1095 Ermengarde de Nevers
  • 2 (their third son) Renaud, seigneur de Courtenay, allegedly married an unnamed sister of Guy du Donjon [who is stated wrongly to have been living in 1148], also described as daughter of Frederic, seigneur du Donjon
    • 3a Elisabeth, died 14 September in or after 1205, married Pierre de France (ancestors of the second French Courtenay line)
    • 3b Unnamed daughter, died sp, married Avalon, seigneur de Saillenay

The name of Elisabeth's sister who married Augalo II of Seignelay was either Adelina or Adelvia - her name was given in a charter for Saint-Jean de Sens abbey dated 1194, read as Adelvia by a copyist in 1729 but as Adelina by the archivist of Auxerre in 1882.

A charter of her husband dated 1190 is not helpful about this, as he referred to her by initial only, "laudavit A., uxor mea".

They had sons named Dainbert and Frederic: it's interestig that the latter name doesn't appear before this in the Seignelay or Courtenay families and possibly came from the step-father of Adelina/Adelvia, Frederic of Donjon, seigneur of Yerres.

The ordinal of her husband should be III, not II, and his name is variously given as Augalo[n], Argalo[n], Avalo[n], and perhaps other forms. It was clearly Agalo on his seal, see here:
