It is unclear how many children Karijotas had. The number varies between 4 and 10. Reliable data is available about four: Aleksander, Yuri, Konstantin, and Fedir, who helped Algirdas, Grand Duke of Lithuania, to defeat the Tatars in the Battle of Blue Waters in 1363. In return, they received Podolia. Aleksander (died ca. 1380) was involved in the fights between uncle Liubartas and Casimir III of Poland. In 1366 Aleksander received Volodymyr-Volynskyi from Casimir for his service against his uncle. Only four years later, after Casimir's death, Liubartas recaptured the city. Yuri (died in 1375 in Moldavia) at first assisted Aleksander, but was poisoned soon after accepting an invitation to become the ruler of Moldavia. Kostantin, after Union of Krewo in 1385, moved to Hungary and died there ca. 1389. Fedir (died in 1414) inherited Navahrudak from his father and after other brothers were dead ca. 1389, became ruler of all Podolia. In 1392 he disobeyed Vytautas the Great and had to run to Hungary, where he ruled Mukachevo and built Palanok Castle.
