The monograph examines the ethnosocial history of Russian Siberians through the prism of the genealogies of peasants, merchants and service people who connected their fate with the Tarsky Irtysh. The appendices contain previously unpublished materials - a fragment of a map of settlements of the Tara district of 1825 and a collapsible book of Tara service people of 1689, which is an important historical and genealogical source on the history of the population of the Tara Irtysh region. The publication is addressed to historians, ethnographers, genealogists, as well as a wide range of readers interested in their pedigree.
