Yuri Dolgorukiy
There are different scholarly opinions as to who exactly was Kata’s spouse. According to a hypothesis commonly accepted by historians in Georgia, she married Isaac Komnenos, the third son of the emperor Alexios I Komnenos, and became Irene, a name recorded by the Byzantine sources as that of Isaac's wife. 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. 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.
