Notes	Robert l, Count of Flanders (c. 1033-1093) was also known as Robert the Frisian. He was count of Flanders (Flandern - Vlaanderen) from 1071 to his death. His parents were Baldwin V of Flanders and Adèle (Capet), a daughter of King Robert ll (Capet) of France. He usurped the countship after defeating his nephew Arnold III and his allies, which included King Philip l of France, count Eustace of Boulogne and the counts of Saints-Pol and Andres at the battle of Cassel. Robert subsequently made peace with Philip, who became his stepson-in-law, but remained hostile to his sister Mathilde and her husband William the Conqueror, who was king of England and duke of Normandy (Normandie). Robert's elder brother, Baldwin (Baldwinsson) Vl, succeeded their father as count of Flanders in 1067 (he died in 1070). Robert's nickname, "the Frisian" was obtained, apparently when he acted as regent for his stepson, count Dirk V of Holland. In 1063 Robert l, Count of Flanders married Gertrude of Saxony, dowager countess of Holland, and they had 6 children: Robert II, who became count of Flanders. Adelais (died 1115), who became queen of Denmark and was married to Canute (Knud) of Denmark. Gertrude, who became duchess of Lorraine. Philipp. Ogiva, who became abbess of Messines. Baldwin, died before 1080. Robert ll had Baldwin VII, Count of Flanders. Adelais had Charles, who married Margaret of Clermont, who also married Thierry d'Alsace, and was the mother of Philip d'Alsace, count of Flanders, and Margaret.
