The identity of lesbian-mother combines a marginalized identity with one of the most revered mainstream identities. With data collected through exploratory in-depth interviews from nine lesbian-mothers, the authors use symbolic interaction framework to explore the strategies that lesbian birth mothers and comothers employ to gain acceptance for their marginal-mainstream identities in their family networks. Respondents experienced varying levels of resistance from their social networks, with comothers being especially vulnerable due to their lack of both biological and legal substantiation. The authors (...) explore the process of identity negotiation in three realms of everyday experience: in relationships with extended families, in relations within the nuclear family, and in lesbian relationships that have ended.
