  Research Notes:

The Genealogica Comitum Flandriæ Bertiniana names "filiam Bernardi Saxonum comitis Gertrudem" as wife of "Robertus", specifying that she was "viduam Florentii comitis Fresonum". The Chronologia Johannes de Beke records the marriage of Count Floris and "Gertrudim filiam Hermanni ducis Saxonum", "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. The Genealogia ex stirpe Sancti Arnulfi names "Idam Namucensem…uxorem Angelberti marchionis et Gertrudem comitissam Flandrensem" as children of "Bernardum". The Annales Egmundani specify that Robert acquired the "comitatum Hollandiæ et Fresiæ" by marrying Gertrud.

[The necrology of the abbey of Saint-Denis records the death "XV Kal Aug" of "Gertrudis comitissa". It is uncertain whether this entry relates to the widow of Count Floris and Count Robert.] Beke's Egmondsch Necrologium records the death "IV die Aug" of "Gheertrudis…" and her burial in Flanders. [A manuscript catalogue of benefactors to Eversham monastery records the death “1 aprilis” 1113 of “Robertus Hierosolymitanus...Gertrudis mater eius”. The accuracy of this source is unknown. The latest date recorded is 1629, but it is not known whether the document represents a later compilation based on earlier sources.] ¹
