Vasilko Bryacheslavich
Vasilko Bryacheslavich (died 1297) was a Polotsk-line Rurikid prince of Vitebsk, probably a son of Bryachislav Vasilkovich. Prince lists place him ruling Vitebsk in 1280—1297. A later genealogy makes him the grandfather of Maria of Vitebsk, wife of Algirdas of Lithuania from 1318.
