Mihailo Dinić supposed that he could be the same person as junak sevastokrator, who is attested in the record written in the Serbian language by the monk Jevsevije (Se pisahъ azь posledni vь inocehь i grešni Evьsevie, rodomь Srьbinь ōt plemena po ōtcu Nikoličina, po materi že Rastisala. Ōtcu ime Borša a materi Elena, vnukь junaka sevastokratora; vь junosti že bihь sluga cara turskogo Ilьdrimь Bajazita bežavь že ōt cara togo vь Svetoju Goru postrigohь se). This record is in the manuscript, which has been preserved in the collection of the Čudov Monastery (State Historical Museum in Moscow, Čudovskoe sobranie, Nr. 15, fol. 1r). It is a copy of a russian transcript of the work Dioptra by Philippos Monotropos, originally written at Constantinople after 1389. Nebojša Porčić proposes a hypothesis, that Junak de Manolo was a Greek and came from the Byzantine Empire. It is also most unlikely that he was identical with Junacь, who according to the Life of the Saint Serbian King Stefan Uroš III Dečanski written by Grigorij Camblak (Gregory Tsamblak), was harassing the monks at the Visoki Dečani Monastery after the death of Stefan Uroš IV Dušan. As Junac saw the Saint Stefan Uroš III Dečanski in a dream, he fell ill and died after seven weeks. Junak de Manolo is mentioned in the charter of Vladislav II, the son of the Serbian King Dragutin, for the comes (knez) and the Consilium Minor (malo veće) of the Ragusan republic from 25th October 1323. He appears as sevast in the charter. Vladislav II, the son of the Serbian King Dragutin, wrote to the goverment of the Ragusan republic, that the merchant Klime Držić and his brothers payed off their debts. Therefore Vladislav II allowed them again to freely trade their goods in his realm. Junak de Manolo was among the witnesses of the charter (E di ço son guarenti lo jupan Rodosclauo, lo jupan Voichna et lo protobistal Jurech, sevast Junac de Manolo, conte Mençe et Marino de Prodanello et Sime de Marcus et Nichola de Naugne).
