The House of Vorontsov (Russian: Воронцо́в), also Woroncow and de Woroncow-Wojtkowicz, is the name of a Russian noble family^[1] whose members attained the dignity of Counts of the Holy Roman Empire in 1744 and became Princes of the Russian Empire on 6 April 1845, with the style of Serene Highness.^[2][3] Most likely, the Vorontsovs represent a collateral branch of the great Velyaminov family of Muscovite boyars, which claimed male-line descent from a Varangian nobleman named Šimon.^[4] The Velyaminovs served as hereditary mayors of Moscow until the office was abolished by Dmitry Donskoy (Prince of Moscow from 1359 to 1389), whose mother Alexandra came from this family.^[5]
