Judith ( also named Maria in some sources ) was the youngest of the six children born to Emperor Henry III and Empress Agnes.

Her older five siblings were: Adelaide ( later Abbess of Quedlinburg ), Gisela ( who died in infancy before her birth ), Matilda ( later wife of Rudolf of Rheinfelden, Duke of Swabia and Antiking ), Henry IV, Holy Roman Emperor and Conrad II, Duke of Bavaria ( who also died in infancy ).

In addition, Judith had an older half-sister, Beatrix I, Abbess of Quedlinburg and Gandersheim, born from her father's first marriage with Gunhilda of Denmark.
