Commentary
Weis lists her as Adele/Adela (d 961), the daughter of Lambert, Count of Louvain. Charles Cawley lists her as Adela (d 961), the daughter of Hugo a count in Nordgau (d 940, son of Count Eberhard and Adelinda) and Hildegarde.
Charles Cawley: "she is named in secondary sources as Adela von Dachsburg, daughter of Hugo [V] Graf von Dachsburg und Egisheim [Alsace] & his wife Hildegard. The Annales Hanoniæ record the death in 961 of "Adela comitissa Montensis…uxor Ragineri comitis", although as this passage follows closely on those dealing with the exploits of "Raginerus Longi-colli" it is unclear to which Count Reginar the Annales are referring at this point. The primary source which confirms her parentage has not yet been identified."
