Roman Svyatoslavich

His former allies, the Cumans killed him after their unsuccessful joint campaign against his uncle, Vsevolod I of Kiev.

[5] According to Martin, he seems to have succeeded his brother Oleg who moved to Vladimir after their father became Grand Prince of Kiev in 1073.

[6] The Russian Primary Chronicle writes that Boris Vyacheslavich "fled to join Roman in Tmutorakan"[7] after reigning in Chernigov for eight days in May 1077.

[12][13] They advanced as far as the confluence of the rivers Sula and Dnieper, but Vsevolod made a peace with the Cumans, forcing Roman to withdraw.

The bones of Svyatoslav's son and Yaroslav's grandson still lie there even to this day.No source makes mention of Roman's marriage or his descendants, implying that he never married and died childless.
