This article carries out a study of the baptismal names given to the boys and girls of a Lutheran and evangelical community in Curitiba, originally composed of German immigrants and their descendants. The data gathered from the baptism registries dating from 1866 to 1987 were classified by types and were the object of a frequential analysis. The results helped establish relationships between the onomasiological practices and the integration process of this ethnic and religious group into the receiving society. Subjected to the tension between their loyalty to their origins and the need to adjust to the new world, the members of this community used two different ambiguous procedures: using first names that could be considered both Germanic and Brazilian, and intensifying the internationalization of feminine baptismal names, thus preserving Germanic masculine first names. Therefore, they found a compromise solution which, in this area of social organization allowed them to be integrated without losing their identity.
