This paper concerns 18th century surnames of Bielsk Podlaski inhabitants based on first names. Analysis of reference material has demonstrated that the majority of surnames of people living in Bielsk Podlaski in the 18th century was based on first names which were anthroponyms of Eastern-Slavonic origin (Antychowicz, Chilkiewicz, Dmitrowicz, Korniluk, Naucik etc.). Surnames originating from Polish first names account for a minor percentage of all analyzed anthoponyms (Maciejuk, Michalewicz, Piotrowicz, Szymonowicz, Urbanowicz). Only single examples indicate the non-Slavonic origin of the analyzed surnames of Bielsk Podlaski inhabitants (Hencmanowski, Iczewska).
