The practice of a woman assuming her husband's last name upon marriage is a deeply embedded norm in some countries. Whether or not individual heterosexual couples reproduce or resist this practice, it provides a context for making decisions about marital names. No conventions, other than heteronormative ones, govern naming practices in same-sex relationships and families, but very little is known about name changing in these contexts. This paper reports an exploratory qualitative study of the ways in which 30 lesbians and gay men in committed relationships made meaning of name changing and keeping. Only one participant reported changing her last name, some considered name changing a future possibility, but most had no plans to change their name. The lack of conventions regarding naming in same-sex families created a dilemma for some participants-who would take whose name? Many participants did not want to entirely give up their name, thus a hyphenated last name was the most popular option for those contemplating a name change. Accounts of name changing centred on doing/being family. This was also a theme in accounts of name keeping, along Maree Burns is the co-ordinator of the Eating Difficulties Education Network in Auckland, New Zealand. Maree has published several articles examining the discourses and discursive practices of the 'eating disorder' bulimia. She has recently completed ESRC-funded research on money management in same-sex relationships with Carole Burgoyne and Victoria Clarke at the University of Exeter. Maree is currently co-editing two books: Critical Feminist Perspectives on Eating Dis/Orders and Critical Bodies: Representations, practices and identities of weight and body management. with maintaining a continuity of personal and professional identity, avoiding hassle, complications and confusion and resisting heteronormativity. The findings are discussed in relation to other research on naming in same-sex families and research on heterosexual marital naming practices.
