Although the presence of some Jews in the city has been confirmed in earlier ages, their continuous stay in Zagreb can be traced back to the beginning of the 19th century and the first censuses from 1808 (for the municipal jurisdiction) and 1812 (for the bishopric jurisdiction). Following the anthroponymy of Zagreb Jews from these censuses to the beginning of World War Two in today’s Croatia (in which the community was decimated), this paper analyses several of its components based on three sources: Gavro Schwarz’s book Povijest zagrebačke židovske općine od osnutka do 50-tih godina 19. vijeka (History of the Zagreb Jewish community from its foundation to the 1850s; Zagreb, 1939), the Jewish registers of birth from 1849 until 1898. (omitting the year 1857), and the data collected from the Jewish section of the Old Cemetery at Mirogoj, which is threefold: inscriptions in Latin script, inscriptions in Hebrew script and the Gradska groblja database available on-line. The data analysed include: the civic first names (/ kinnūy/ “nickname”) of Zagreb Jews, their frequency, origin and languages from which they were directly loaned, with a diachronic approach to the frequency of particular source languages of first names and languages from which first names were directly loaned; Jewish first names (/ šem-haqqodæš/ “sacred name”), their frequency and their etymological structure; relationships and links between individual civil and individual Jewish first names and diachronic representation of the frequency of their most popular combinations. All these researches are performed separately for male first names and for female first names. As far as family names are concerned, their etymology is analysed, as well as the frequency of individual source languages. We also analyse the changes of family names and the family names recorded in Hebrew script.
