Family of Gediminas
It is unclear why, but Jaunutis, a middle son not mentioned in any written sources before the "coup d'état" accomplished by his brothers, was designated by Gediminas as his heir in Vilnius and consequently became the Grand Duke. His brother Kęstutis, Duke of Trakai, was assisting him in Samogitia. Despite help from Narimantas, Jaunutis was deposed by his brothers Algirdas and Kęstutis in 1345, just four years after Gediminas' death. Jaunutis tried, but failed, to solicit help from his brother-in-law Simeon of Russia and was baptized as "Iwan" in the process. He was forced to reconcile with Algirdas and in compensation received the Duchy of Zasłaŭje, which he ruled until his death in 1366.

Several sons of Gediminas continued his male line, but it was Algirdas who continued the main Gediminid line. Before deposing his brother Jaunutis in 1345, he ruled Kreva and, despite remaining pagan, married Maria, a daughter of the last prince of Vitebsk. After 1345 he became the Grand Duke of Lith

Family of Gediminas [SEP] Sons
The chronicle of John of Winterthur contains a reference to Gediminas' eight sons. The names of seven sons can be found in various written sources, while the identity of the eighth remains disputed. Alvydas Nikžentaitis suggests that this son was the Duke of Trakai who perished in 1337 in the attack on Bayernburg. Duke of Trakai was an important position held either by the Grand Duke himself or his second-in-command. Therefore, 18th- and 19th-century historians believed that it was Gediminas himself who died at Bayernburg. Nikžentaitis further postulates that the name of the unknown son might have been Vytautas, as records mention a young and powerful Yuri, son of Vytautas and deputy of Andrei, son of Algirdas.
