This article describes the contents of the letters written in 1889–1919 by Adolf Černý to the siblings Alfons and Melania Parczewski in Kalisz, which are preserved in the Lithuanian National Historical Archives in Vilnius. They concern the personal and scientific-literary relations between the correspondents, and the subject of Lusatia is often raised. The presentation of their contents is preceded by information on Adolf Černý’s letters that had been previously published as well as a biographical sketch of their author and his addressees. Melania Parczewska was a writer, publicist and translator as well as a social, cultural and political activist, and her brother, the lawyer Alfons Parczewski, was a social and political activist and defender of minorities’ rights.
