ALBERT de Namur, son of ALBERT II Comte de Namur & his wife Regilindis of Lower Lotharingia (before 10 Aug 1035-22 Jun 1102). The Genealogica comitum Buloniensium records that "Albertum comitem de Namuco" was father of "Albertum et fratrem eius Heinricum comitem de Durboio"[64]. He succeeded his father in [1063/64] as ALBERT III Comte de Namur. He claimed to succeed to the inheritance of his first cousin Godefroi III "Le Bossu" Duke of Lower Lotharingia in 1076, challenging the succession of Godefroi de Bouillon [Boulogne] and at one point unsuccessfully besieging the castle of Bouillon. As guardian of her interests in Lotharingia, Matilda of Tuscany granted Albert the county of Verdun which Theoderic Bishop of Verdun had bestowed on her in 1076, in order to thwart Godefroi de Bouillon´s inheritance[65]. In addition, Emperor Heinrich IV appointed Albert as vice-duke of Lower Lotharingia in 1076 to rule for his infant son Konrad, whom he had installed as Duke of Lower Lotharingia[66]. "Heinricus…tertius Romanorum imperator augustus" confirmed the foundation of St Jakob, Liège by "Albertus comes Nammucensium filiis [suis] Godefrido, Heinrico, Alberto" by charter dated 1 Jun 1101[67]. The Notæ Bronienses record the death in 1102 of "Albertus comes Namucensis"[68]. The necrology of Brogne records the death "X Kal Jul" of "Adalbertus comes Namurcensis"[69].

"Ida" is named as wife of "Albertus comes Namucensis" in the Chronicon Sancti Huberti, which specifies that "prius fuerat uxor ducis Frederici", but her origin is not given[70]. The Genealogia ex stirpe Sancti Arnulfi names "Idam Namucensem…uxorem Angelberti marchionis et Gertrudem comitissam Flandrensem" as children of "Bernardum"[71]. On her marriage, she brought her husband extensive lands north-east of the castle of Bouillon which later formed the county of Laroche[72]. According to the Chronicle of Alberic de Trois-Fontaines, her husband's claim to Bouillon was through the property brought by his wife[73]. The necrology of Brogne records the death "II Kal Aug" of "Ida comitissa Namurcensis"[74].
Comte Albert III & his wife had five children
