FLORIS ([1025]-murdered Hamerth 28 Jun 1061, bur Egmond). The Annales Egmundani names "Florentius I" as brother of "Theodericus IIII comes filius Theoderici et Othelhildis" when recording that he succeeded his brother[318]. The Chronologia Johannes de Beke names "Theodricum succedentem Hollandia principum et Florencium Orientalis Frisie comitem" as children of Count Dirk III & his wife[319]. "Heinricus…rex" confirmed a treaty between Wilhelm Bishop of Utrecht and Reginbert Abbot of Echternach under which they recognised each other's rights in "Flardinge, Kiericwerve, Velsereburc, Heligelo, Pethem" by charter dated 28 Dec 1063 which names "Theoderico comite ac filio eius Theoderico fratreque eius Florencio"[320]. He succeeded his brother in 1049 as FLORIS I Count of Holland. The Annales Egmundani record that "Florentius comes Hollandensis" was killed in 1061 at "Hamerthe"[321]. The Chronologia Johannes de Beke records the death "1061…in Hamerth…XIV Kal Iun" of Count Floris and his burial at Egmond[322]. Beke's Egmondsch Necrologium records that "Florentius primus Hollandie comes" was killed in battle "1061 IV Kal Iul"[323]. m ([1050]) as her first husband, GERTRUD of Saxony, daughter of BERNHARD II Duke of Saxony [Billung] & his wife Eilika von Schweinfurt (Schweinfurt [1028]-Veurne 4 Aug 1113, bur Veurne). The Chronologia Johannes de Beke records the marriage of Count Floris and "Gertrudim filiam Hermanni ducis Saxonum"[324], "Hermanni" being an error for "Bernardi" as the former would be impossible chronologically. The Genealogica Comitum Flandriæ Bertiniana names "filiam Bernardi Saxonum comitis Gertrudem" as wife of "Robertus", specifying that she was "viduam Florentii comitis Fresonum"[325]. "Theodericus…Holtlandensis comes…Florentii filius" recites the ownership history of properties claimed by the church of Utrecht in Holland, including donations by "Florentius, tercii Theoderici filius, cum bone memorie uxore sua Gerthrude", by spurious charter dated 26 Jul 1083, probably written [1130][326]. She married secondly (1063) Robert de Flandre ([1035]-13 Oct 1093), who was regent of Holland for his stepson until 1071, when he succeeded as Robert I Count of Flanders. The date of her second marriage is based on the Chronologia Johannes de Beke recording that, two years after the death of her first husband, Gertrud married "Roberto iuniori filio Balduini comitis Flandrie", specifying that the latter ruled the county of Holland on behalf of "Theodrici domicelli iunioris adhuc etatis"[327]. "Gertrudis" is named as wife of "Roberti Frisonis" in the Cartulaire de Saint-Bertin, which does not give her origin[328]. The Genealogia ex stirpe Sancti Arnulfi names "Idam Namucensem…uxorem Angelberti marchionis et Gertrudem comitissam Flandrensem" as children of "Bernardum"[329]. The Annales Egmundani specify that Robert acquired the "comitatum Hollandiæ et Fresiæ" by marrying Gertrud[330]. The necrology of the abbey of Saint-Denis records the death "XV Kal Aug" of "Gertrudis comitissa"[331]. Beke's Egmondsch Necrologium records the death "IV die Aug" of "Gheertrudis…" and her burial in Flanders[332]. Count Floris & his wife had [four] children
