Mentioned in the chrysobull charter of the Serbian Emperor Stefan Uroš IV Dušan for Iakobos (Iakovь), the Metropolitan of Serres, concerning the Church of Saint Nicholas on the river Pčinja beneath the fortress of Kožle from 1352/1353. His brother was Nane. The Serbian Emperor Stefan Uroš IV Dušan together with his son and his wife donated the Church of Saint Nicholas on the river Pčinja under the fortress Kožle, which was founded by his grandfather Stefan Uroš II Milutin, for life to the metropolitan of Serres. They granted him all rights of the church together with the land, the people, the vineyards, watermills, bought estates, estates given for the sake of soul and hunting grounds. After the death of Jakob, the metropolitan of Serres, the rights should devolve on the Monastery of the Holy Archangels Michael and Gabriel near Prizren. Among the donated people were freemen from the Byzantine Empire, who came at the time when the Turks plundered Anatolia and were well received on the churchʼs land by the Serbian King Stefan Uroš II Milutin. Their arrival might have a connection with the presence of the Serbian troops under the command of Novakь Grěbostrěkь in Anatolia. One of the migrants was Murьtatь (I kьdi plěniše Turʼci Anatoliju, tьdii prïidoše slobodni ljudije izь Grьkьь na crьkovnu zemlju pri svetomь krali; a se imь imena: Gradislavь, Radь Ohreda, Murьtatь Nanevь bratь).
