Mentioned in the charter of Ioan Uglješa (Ioannes Unklesis) from January 1366, in which the Serbian Despot confirmed the donation of Novakь Mrasorovikь to the Monastery Hagios Panteleemon on the Holy Mount Athos. He was probably a duke [the reading of Novaković (vojevoda) and Solovjev (voivoda)]. He was the guarantee of the legal accuracy of the charter, which was issued by the Serbian Despot Ioan Uglješa (Ioannes Unklesis) in January 1366.
