Sviatoslav had several children, but the origin of his wives is not specified in the chronicle. By his wives, he had Yaropolk and Oleg.[17] By Malusha, a woman of indeterminate origins,[18] Sviatoslav had Vladimir, who would ultimately break with his father's paganism and convert Rus' to Christianity. John Skylitzes reported that Vladimir had a brother named Sfengus; whether this Sfengus was a son of Sviatoslav, a son of Malusha by a prior or subsequent husband, or an unrelated Rus' nobleman is unclear.
