Boris Godunov was the most noted member of an ancient, now extinct, Russian family of Tatar origin (Chet), which came from the Horde to Kostroma in the early 14th century. This legend is written in the annals dating from early 17th century. He was descended from the Tatar Prince Chet, who went from the Golden Horde to Russia and founded the Ipatiev Monastery in Kostroma. Boris was the son of Feodor Ivanovich Godunov "Krivoy" ("the one-eyed") (died, c. 1568–1570) and his wife Stepanida Ivanovna. His older brother Vasily died young and without issue.
