The article reviews Nadezhda Woytinskaya's manuscript letters to her brother Wladimir Woytinsky. Nadezhda Woytinskaya was an artist, translator and writer. Wladimir Woytinsky was a revolutionist, economist and specialist in statistics. In the letters, the Woytinskies family members are mentioned and some important for them events that happened in the period of writing (from 1911 to 1917) are described. The stylistics and the content of these letters are typical for Russian intelligentsia's epistolary heritage, yet sometimes the problems specific for everyday life of a Jewish family in the pre-revolutionary Russia are brought up there.
