Heraclius II of Georgia
A member of the prominent Georgian noble house with family ties with the Bagrationi royal dynasty, David Orbeliani was a hereditary prince of Sabaratiano, Constable of Somkhiti, and a high-ranking military commander under King Heraclius II of Georgia whose daughter, Tamar (1749-1786), married him at Tbilisi in 1762. In 1786, he ran afoul of Heraclius II, who stripped him of the office of Grand Master of the Court ("sakhlt-ukhutsesi") and granted it to Ioann, Prince of Mukhrani.
