This article deals with naming practices among the Czechs who lived in the first half of 20th century in two Bulgarian villages - Vojvodovo and Belinci. It is based on fieldwork carried out among the people who migrated in 1950 from Bulgaria and settled in several towns and villages in South Moravia (region of Mikulov and Valtice), and their descendants. Naming practices of the Bulgarian Czechs are analyzed in relation to naming strategies of the Bulgarians in the given period, and it is argued that the role that was fulfilled by surnames among the Czechs was fulfilled by first names among the Bulgarians. Relationship between the naming strategies and ideas about kinship and gender are discussed further.
