Adela I van Henegouwen, countess of Louvain - connection

Adela I van Henegouwen, countess of Louvain wife of Régnier (Reginar) III, comte de Hainaut ..
is she the same Adelaide von Dagsbourg daughter Hugo V, count in Nordgau ?

or Adelaide von Dagsbourg is just a profile certainly wife of Régnier (Reginar) III, comte de Hainaut & only '''['''hypothetically''']''' daughter of Hugo V, count in Nordgau ?

I invite you all to this discussion as a last detail after cleaning up this:

1. REGINAR [III] ([920]-973). .. ... .....

m''' ADELA''', daughter of --- (-961). The Annales Hanoniæ record the death in 961 of "Adela comitissa Montensis…uxor Ragineri comitis"[39], 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.
She is named in secondary sources as [Adelaide von Dagsbourg '''Adela von Dachsburg'''], daughter of [Hugo V, count in Nordgau Hugo] [V] Graf von Dachsburg und Egisheim [Alsace] & his wife [Hildegarde de Ferrette Hildegard] ---, but the primary source which confirms that this is correct has not yet been identified.
