Legacy Vita of Michael of Chernigov A hagiography vita of Michael of Chernigov was written some time after his death, describing his life in detail, and framing his execution as martyrdom. It is unclear when this account was written (at least after the Mongol census in Suzdalia and Novgorod in 1257–59), and how historically reliable it is. Mikhail's death is briefly mentioned in the Older Recension of Novgorod First Chronicle (compiled 1275), in the Laurentian Codex (compiled 1377), and in the Hypatian Codex (compiled 1425), but the full text of the vita is not found in these manuscripts. It is not until the Younger Recension of the Novgorod First Chronicle (compiled 1450) that an extensive narrative of his demise appears, stating that the bodies of Mikhail and Fedor were thrown to the dogs; but as a sign of divine favor, their bodies remained unmolested and pillars of fire hovered over them.

Carpine account Giovanni da Pian del Carpine, an Italian papal legate who travelled through the lands of former Kievan Rus' in the late 1240s, wrote the following account of his death in the Ystoria Mongalorum:

Genealogy Marriage and children Michael married once and had several children. Elena Romanovna (or Maria Romanovna) (m. 1210 or 1211), a daughter of prince Roman Mstislavich of Halych and his wife, Predslava Rurikovna of Kiev

In the second half of the 19th century, many family branches stemming from Mikhail flourished: the Baryatinsky, the Gorchakovy, the Dolgorukie, the Eletskie, the Zvenigorodskie, the Koltsovy-Mosalskie, the Obolenskie, the Odoevskie, and the Shcherbatovy.
