Empress Jigda Bagrationi, princess of Georgia

The duration of Jiajak and Alexios's marriage remains uncertain. Alexios died in 1330 but there is no report when Jiajak died. The Dictionnaire historique et Généalogique des grandes familles de Grèce, d'Albanie et de Constantinople (1983) by Mihail-Dimitri Sturdza considers Jiajak to be only the first of two wives. The second one being Jidga, the only daughter of Demetre II of Georgia and his second wife Solghar, a Mongol. Demetre II practiced polygamy and had three known wives at the same time. The existence of this daughter is reported in the "Georgian Chronicles". However, the Chronicle does not mention her being married. However older works such as the Europäische Stammtafeln: Stammtafeln zur Geschichte der Europäischen Staaten (1978) by Detlev Schwennicke do not mention any second marriage for Alexios II. As a result Sturdza's theory is not universally accepted.[4]
