Family
Judith was born between 1030 and 1035 in Bruges, the only child of Baldwin IV, Count of Flanders by his second wife, Eleanor of Normandy, who was herself, the daughter of Richard II of Normandy and Judith of Brittany. Judith had an older half-brother, Baldwin V, Count of Flanders, who succeeded their father upon his death which had occurred when Judith was about two years old. (Some scholars argue that Judith's father was Baldwin V, not Baldwin IV.)
Judith's niece was Matilda of Flanders who married William, the first Norman king of England, known to history as "William the Conqueror". King William was Judith's first cousin, being the son of her maternal uncle, Robert of Normandy.
