Xenia Shestova (nun Martha)
Boyarinya 'Kseniya Ioannovna' (Ivanovna) () was a spouse of
Fyodor Romanov and a mother of
Mikhail Romanov. The origin of Xeniya Ivanovna has been disputed by genealogists for centuries. It is currently accepted that her surname was 'Shestova' (Шестова; rather than Shastunova, as was previously believed) and that her grandfather was Timofey Gryaznoy, a rich landowner from
Uglich.
During
Boris Godunov's repressions against the Romanovs, she was forced to take a veil, changing her name to 'Martha' (Russian: Marfa). After several years of exile at Tolvuyskiy
pogost, she settled with her son in
Kostroma. It was there that the ambassadors arrived to inform Mikhail about his election to the Russian throne in 1613. As the previous tsars had been either killed or disgraced, Marfa at first opposed to bless her son and let him go to Moscow. At last she gave up and blessed him with the icon
Our Lady of St. Theodore, which became the palladium of the
Romanov dynasty.
During the first years of his reign, Marfa (or the "great nun" as she came to be known) exerted great influence on her moribund and listless son. She placed her relatives, the Saltykovs, at the important posts in the government, leading to widespread corruption. The return of her husband from Poland in 1619 put an end to their (and her own) influence at court. She died in
1631.
