Princess Ketevan married George, the eldest son of King Heraclius II and heir apparent to the throne of the Kingdom of Kartli and Kakheti in 1766. The marriage helped the Andronikashvili clan, especially Ketevan's brother Revaz, advance their cause at the royal court against the rival faction patronized by Heraclius II's consort Darejan Dadiani. By 1780, Darejan's party succeeded in reducing the Andronikashvili's influence, convincing Heraclius to remove Revaz Andronikashvili from the bailiffship of Kiziqi. Years later, in 1795, Prince Revaz would prevent the Kiziqian troops from coming to aid to the beleaguered king Heraclius, desperately battling the Persians at his capital city of Tbilisi.
