GERTRUD of Saxony (Schweinfurt [1028]-Veurne 4 Aug 1113, bur Veurne). The Genealogica Comitum Flandriæ Bertiniana names "filiam Bernardi Saxonum comitis Gertrudem" as wife of "Robertus", specifying that she was "viduam Florentii comitis Fresonum"[308]. The Chronologia Johannes de Beke records the marriage of Count Floris and "Gertrudim filiam Hermanni ducis Saxonum"[309], "Hermanni" being an error for "Bernardi" as the former would be impossible chronologically. "Gertrudis" is named as wife of "Roberti Frisonis" in the Cartulaire de Saint-Bertin, which does not give her origin[310]. The Genealogia ex stirpe Sancti Arnulfi names "Idam Namucensem…uxorem Angelberti marchionis et Gertrudem comitissam Flandrensem" as children of "Bernardum"[311]. The Annales Egmundani specify that Robert acquired the "comitatum Hollandiæ et Fresiæ" by marrying Gertrud[312]. The necrology of the abbey of Saint-Denis records the death "XV Kal Aug" of "Gertrudis comitissa"[313]. Beke's Egmondsch Necrologium records the death "IV die Aug" of "Gheertrudis…" and her burial in Flanders[314]. m firstly ([1050]) FLORIS I Count of Holland, son of DIRK III "Hierosolymita" Count of Holland & his wife Othelindis [von Haldensleben-Nordmark] ([1025]-murdered near Hemert 28 Jun 1061). m secondly (1063) ROBERT de Flandre, son of BAUDOUIN V "le Pieux/Insulanus" Count of Flanders & his wife Adela de France ([1035]-13 Oct 1093).
