Mentioned in the painted inscription over the west door of the narthex of the Church of the Virgin Peribleptos in Ōhrid (now Church of Saints Clement and Panteleimon) from 1294/1295. He appears as a κῦρ in the inscription. He held the position of Megas hetaireiarches, 1294–1295. Progonos Sguros was of noble Albanian background. He belonged with all probability to the family of Scura (Sgura). His wife was Eudokia. He was the son-in-law of the Byzantine Emperor (probably Michael VIII Palaiologos). According to the painted inscription over the west door of the narthex from 1294/1295 he commisioned together with his wife Eudokia Komnene the Church of the Virgin Peribleptos in Ōhrid (now Church of Saints Clement and Panteleimon), at that time under Byzantine rule. He was holding the rank of megas hetaireiarches and was through his wife related to the family of Byzantine emperor (Ἀνηγέρθει ὁ θεῖος καὶ πάνσεπτος ναὸς οὗτος τῆς πανυπεράγνου δέσποινης ἡμῶν Θεοτόκου τῆς περιβλέπτου διά τε συνδρομῆς καὶ ἐξόδου κυροῦ Προγόνου τοῦ Σγουροῦ τοῦ μεγάλου ἑταιρειάρχου καὶ τῆς συζύγου αὐτοῦ κυρὰς Εὐδοκίας καὶ γαμβροῦ τοῦ κραταιοῦ καὶ ἁγίου ἡμῶν αὐτοκράτορος καὶ βασιλέως· ἐπὶ τῆς βασιλείας τοῦ εὐσεβεστάτου βασιλέος καὶ αὐτοκράτωρος Ῥωμαίων Ἀνδρονίκου τοῦ Παλαιολόγου· καὶ Εἰρήνης τῆς εὐσεβεστάτης αὐγούστης· ἀρχιερατεύοντος δὲ Μακαρίου τοῦ παναγιωτάτου ἀρχιεπισκόπου τῆς Πρότης Ἰουστινιανῆς καὶ πάσης Βουλγαρίας· ἐπὶ ἔτους· ϛ ω γ ἰνδικτιῶνος η). An epigram embroidered on an altar cloth in the thirteenth or fourteenth century and now kept in the National Historical Museum at Sofia seems to be a gift of the famous megas hetaireiarches and his wife (Δῶρόν σοι κλεινὸς μέγας ἑταιρειάρχης/ τύπον σῆς σταυρώσεως ἀνατυπῶ σοι/ ἐκ τῆς δοκούσης τάχα τιμίας ὕλης/ σὺν Εὐδοκίᾳ τῇ ὁμοζύγῳ, Λόγε,/ οὔσῃ Κομνηνῇ μητροπαπποπατρόθεν/ ἵνα λύσιν λάβωμεν ἀμπλακημάτων).
