Mentioned in the chrysobull charter of the Serbian Despot Ioan Uglješa (Ioannes Unklesis) for the Monastery Simonos Petras on the Holy Mount Athos from 1368. The charter is preserved only in a copy produced in 1622/1623 during the Patriarchate of Kyrillos Lukaris. He had two brothers (Nikolaos and Georgios). He sold together with his brothers their possession between the villages Bernarus and Esphagmenu near Serres to the Serbian Despot Ioan Uglješa (Ioannes Unklesis) for 879 nomismata. The Serbian Despot Ioan Uglješa (Ioannes Unklesis) donated their former possession to the Monastery Simonos Petras on the Holy Mount Athos (Ἐν δέ τοῖς μέρεσι τοῦ στρώμονος, ὑπάρχει μετόχιον ἀναμέσον τῶν δύω συνόρων τοῦτε Σεῤῥῶν καί τῶν Ζυχνῶν, φημί, ἐν ᾧ ὑπάρχει κλῆτος, αὐτό καθ’ αὐτό κεχωρισμένον ἐκ τῶν ἀνέκαθεν καιρῶν ὁ δ’ αὐτός χῶρος ξύμπας, ἐτύγχανε κτῆμα κῦρ Γεωργίου τοῦ στρατηγοῦ μετά τῶν αὐτοῦ αὐταδέλφων Νικολάου, καὶ Δημητρίου, ὑπάρχει δέ μεταξύ τῶν δύω κομῶν τοῦ τε βαρνάρου καὶ ἐσφαγμένου, ἐξωνησάμην δέ καί τό αὐτό κλῆτος, παρά τῶν πρό μικροῦ ἄνωθεν εἰρημένων αὐταδέλφων ἅπαν διά νομισμάτων ὀκτακοσίων ἑβδομήκοντα ἐννέα).
