Kata or Katay (Georgian: კატა, კატაჲ) was a daughter of David IV, King of Georgia.
[2] The chronicle extols Kata and her sister, Tamar, a wife of the shah of Shirvan, as luminaries of the West and the East, respectively, reflecting the splendor of their father.
If the hypothesis is true and Helene, a daughter of Isaac and Kata, was indeed the wife of the Rurikid Rus' prince Yuri Dolgorukiy, then it may provide, through descent from antiquity, a Bagratid ancestry to numerous Russian and Polish descendants.
[5] Alternatively, Isaac's wife Irene may have been the same person as an anonymous daughter of Volodar of Peremyshl known from the Slavonic Primary Chronicle to have married the likewise unnamed son of the emperor Alexios.
[1] The Byzantine chronicle of Joannes Zonaras mentions the arrival of the Georgian (Abasgian) bride of the elder son of John II at Constantinople immediately after his accession to the throne, not long after 1118.
