St. Xenia was the wife of Colonel Andrei Feodorovich Petrov, who served as a court chanter. At the age of 26, Xenia was widowed and, appeared to have lost her mind from grief: she distributed her possessions to the poor, dressed herself in the clothes of her reposed husband, and, as if having forgotten her own name, called herself by the name of her reposed husband - Andrei Feodorovich.
