• 1. ROBERT [I] ([920/25]-before 981). ... m ---. Thierry Stasser suggests that the wife of Robert [I] Comte de Namur may have been [Liutgarde], daughter of Adalbert Graf [von Metz], emphasising that this is purely speculative based only on onomastics[21]. Comte Robert [I] & his wife had [five] children:
  • a) ALBERT (-shortly before 1011). Albert, Gislebert and Ratbod are named as sons of Comte Robert in a charter dated 981[22]. He succeeded as ALBERT I Comte de Namur. - see below.
  • b) GISELBERT ([955/60]-). The Gesta Abbatum Lobiensium records that "Gislabertus, ex quatuor comitis Roberti filiis unus" accompanied "Mathildem comitissam" to the abbey of Lobbes[23]. This event is not dated but is recorded in the Gesta several paragraphs after an event dated to 974. His birth date range is estimated on the assumption that Giselbert was a young adult when he visited Lobbes, dated some time between 975 and 980. Albert, Gislebert and Ratbod are named as sons of Comte Robert in a charter dated 981[24].
