This paper discusses language use and identity patterns in ethnic minority/ethnically heterogeneous multigenerational deaf families in Romania, where at least one of the family members belongs to the ethnic Hungarian minority. Early childhood and school linguistic socialization, language use within the family, and cross-generational transmission of identity to children are explored. The research is based on five ethnic minority/ethnically heterogeneous multigenerational deaf family case studies. The research results show that within ethnic-national minority/ethnically heterogeneous multigenerational deaf families, complex identity patterns may develop and multifaceted linguistic communication models may prevail, including the use of national oral languages and national sign languages of the parties involved. At the same time, a kind of special linguistic and cultural enrichment, a striving for cultural-linguistic balance, may occur.
