Boris died after a lengthy illness and a stroke on 13/23 April 1605. He left one son, Feodor II, who succeeded him and ruled for only a few months, until he and Boris' widow were murdered by the enemies of the Godunovs in Moscow on 10/20 June 1605. Boris's first son, Ivan, was born in 1587 and died in 1588. His daughter, Xenia, was born in 1582. She was engaged to Johann of Schleswig-Holstein, but he died shortly before their planned wedding in October 1602. Xenia was given the name "Olga" upon being forced to take monastic vows at the Voskresensky Monastery in Beloozero and her name is inscribed as "the Nun Olga Borisovna" at the crypt of the Godunovs at the Trinity Lavra of St. Sergius where she lived from 1606, when she sojourned there to attend the reburial of her father, until her death in 1622. Boris, his wife, and their children are buried together in a mausoleum near the entrance of the Assumption Cathedral at Trinity-St. Sergius Lavra.
