In the Rus chronicles there is no information about Matilda, her Russian name is unknown. The daughter of Prince Yaropolk Izyaslavich and Kunigunda (Irina) von Orlamünde, apparently, was born in Turov, but was taken by her mother to Germany after the death of Yaropolk. She lived with Kunigunde in the Margrave of Lausitz, where Kunigunde remarried to Kuno of Northeim, as it is mentioned in German chronicles [I, p. 321; II, p. 693]. The Saxon chronicler reports about the wedding of an unnamed daughter of Kunigunde and Yaropolk with Count Günther of Köfernburg [ibid.]. N. Baumgarten suggested that the marriage was concluded after 1087, i.e. after the death of Yaropolk [2, P. 10. Table II. N 7] The assumption that the princess's name was Matilda can be made on the basis of the fact that her son, Sizzo III named one of his daughters Methilda (Matilda), probably in honor of his mother [5, s. 33]. It is known about the four children of Matilda and Günther: Sizzo, the founder of the Schwarzburg sovereign house, and Friedrich, and daughters Adela and Bertha [4, s. 52]. Some researchers believe that Matilda remarried (the reason for the divorce from Günther is unknown) to Wprecht the Elder, Margrave of Meissen and Lusatia, but traditionally it is believed that Wiprecht was the third husband of Matilda's mother Kunigunde [3, p. 144; 6, p. 13].
