Research Notes:

The Genealogica Arnulfi Comitis names "Adelam, domni Heriberti comitis filiam" as wife of "comes Arnulfus", specifying that she was "duorum Francorum regum, Odonis atque Rotberti, neptem." Flodoard refers to the wife of "Arnoul" as sister of "Hugo [de Vermandois Archbishop of Reims]". Her marriage was arranged to seal the alliance made in 934 between her father and her future husband. "Arnulfus Flandrie comes et marchisus" granted use of property "Snellenghem in pago Flandrensi" to Saint-Pierre de Gand, for "uxore mea…Adala atque…filio meo Balduino et filia mea Lietgardis" and for deceased "Balduino genitore meo et Elstrudis genetrice mea atque Heeberto filio meo", by charter dated 10 Jul 953. "Adhela comitissa" freed two serfs and granted them to the abbey of Saint-Pierre de Gand, for the soul of "fidelis nostri Amalrici", by charter dated 8 Sep 954, signed by "Balduini comitis…Odacri advocati".

The Annales Blandinienses record the death in 960 of "Adala comitissa". ²
