This article is devoted to the quantitative and qualitative analysis of anthroponyms of Eastern European origin appearing in the surnames of contemporary residents of Chelm (Poland). On the basis of collected material the authoress attempts to describe the semantics and etymology of anthroponyms in which phonetic and word formative elements were discovered, all of them being a part of Eastern Slavic (Ukrainian in particular) language system. What needs to be underlined is the fact that the presence of eastern Ukrainian elements in surnames of contemporary Chelm dwellers is connected with the migration of Poles and Ukrainians, situation of the town and its social and political position in history.
