  Research Notes:

The Genealogiæ Scriptoris Fusniacensis names "Robertum regem et filiam Hadevidem…comitissam Hainonensium" as the children of King Hugues. The Chronicle of Alberic de Trois-Fontaines also names "soror regis Roberti Hadwidis" as wife of "Rainero comiti de Hainaco, fratri Lamberti comitis de Lovanio". Sigebert's Chronica records in 977 that "Raginerus" married "Hathuidem filiam Hugonis postea regis". "Comes Raginerus et Hathuidis coniux" are named in the Gesta of Gembloux Abbey. Her brother gave her the towns of Couvin, Fraisne, Nîme, Eve and Bens [all now in Belgium] as her dowry on her marriage. "Raginero comite…et Hathuidis coniunx eius" donated property at Gion to Gembloux by charter dated to [1013]. "Heinricus…Romanorum imperator augustus" took into his protection the abbey of Florennes founded by "Gerardus…in primis meus capellanus postea…Cameracensis episcopus effectus et fratres sui Godefridus et Arnulphus" by charter dated 1018, which refers to earlier donations of property by "comitissa Hawidis, annuentibus filiis suis comite Raginero et Lamberto". "Chuonradus…Romanorum imperator augustus" confirmed the foundation of Florennes abbey by charter dated 1033, which records among others the donation of "comitissa Hadegundis, annuentibus comite Raginero et Lamberto filiis suis…in Prona sita in pago Haynomensi". The identity of "comitissa Hawidis/Hadegundis", and therefore the existence of Lambert, supposed brother of Reginar [V] Comte de Hainaut, is not certain. Hedwige, wife of Reginar [IV] Comte de Hainaut, is the most obvious candidate. If this is correct, the donation must have been made after her husband's death in 1013 as he is not named in the document. The other possibility is that the donor was the mother of Reginar [IV] Comte de Hainaut and his brother Lambert [I] Comte de Louvain. However, the name of the wife of their father, Reginar [III] Graf im Maasgau, is recorded elsewhere as Adela... ¹
