Most research on migration and ethnic boundaries is concerned with boundaries between a specific migrant minority and the ‘majority society’ in the destination country. However, migrant groups are not homogenous; within-group boundaries that are relevant in their context of origin may also play a role in the host context. Focusing on migrants from former Yugoslavia, we analyse the relevance of ethnic boundaries between Bosniaks, Serbs and Croats in Germany. We do so by interpreting migrant parents’ practices of first-name giving as instances of ethnic boundary work. In the case of migrants from former Yugoslavia, first names are a salient marker of ethnic affiliation. Based on 22 semi-structured interviews, we distinguish between three types of ethnic boundary work based on first-name giving. ‘Particularists’ wish to express their ethnic affiliation via first names, and they maintain ethnic boundaries both towards the German majority society as well as other ethnic groups from former Yugoslavia. In contrast, ‘cosmopolitans’ reject names with specific ethnic references and base their choice on personal taste, often opting for international names, thereby rejecting ethnic boundaries towards other former Yugoslav groups. Finally, ‘negotiators’ stand in between. They blur boundaries towards the German majority society, but maintain boundaries towards other ex-Yugoslav ethnic groups. Overall, we find that ex-Yugoslav migrants’ strategies of ethnic boundary work are shaped by a multiplicity of reference groups, not just the relationship with the German majority society
