Abstract: Until recently, the genealogy of the family of the great Russian architect and painter Vasily Ivanovich Bazhenov (1738-1799) was little studied, full of inaccuracies and misconceptions. A little fragmentary and not always accurate information about the children and grandchildren of the architect was presented mainly in the works of Y. Y. Gerchuk and E. I. Ilizarova. However, until now, for example, the exact dates of life and burial places of members of the architect's family were unknown. The author of the present research studied church books, confession lists, archival court cases and many other archival documents and found a lot of new and previously unpublished information about the children of Vasily Bazhenov and his wife Agraphena Lukinichna (1745-1817): Konstantin (1771-1826), Vladimir (1772-1820), Olga (1773-not earlier than 1825), Vsevolod (1774-1843), Voin 1 (1776-1779), Nadezhda (1778-1857), Voin 2 (1779-1784), Mstislav (1782-1783), Vera (1784-not earlier than 1834) and Voin 3 (1785). The relevance and novelty of the study lies in the publication and systematization of many previously unknown facts from the history of V. I. Bazhenov's family, which significantly expands the understanding of the outstanding architect. The article presents the results of field survey of the Bazhenovs' burial sites in the Nizhny Novgorod Oblast and the Republic of Mordovia on the subject of the burials' preservation, these results are also important for necropolistics. The study provides dates of life, dates of marriages, as well as information about family, property, official status, family composition, places of residence, burial, etc., which allowed to reconstruct the genealogical picture of the family of the architect V. I. Bazhenov and his offsprings quite completely.
