In 1043, Gertrude married Iziaslav I of Kiev, with whom she had two sons: Yaropolk Iziaslavich and Mstislav, and a daughter, Eupraxia, who later married Mieszko Bolesławowic of Piast dynasty, the Prince of Kraków.[2] Often acknowledged as her son,[3] Sviatopolk II of Kiev may have been the son of Izyaslav by a concubine.

Gertrude inherited a medieval illuminated manuscript, known as the Egbert Psalter or Trier Psalter, which had been created in the late 10th century for archbishop Egbert of Trier. She included her prayer book as part of the codex. In the prayer book she prays six times for Yaropolk, unicus filius meus (translated as either "my favourite son" or "my only son").
