DNA analysis has enabled a much deeper interrogation of our surnames, Keesing and Fitzpatrick, than was possible via traditional genealogical research. This can inform us regarding the potential ‘hidden’ complexities of some surnames. Through juxtaposing the narratives of our family histories and DNA findings we demonstrate, using collaborative autoethnography, how surnames can be haunted by ghosts both real and imagined. The DNA-enabled critical exploration of the history of our surnames, in the context of the social and political factors that shaped them, generates a deeper and more complex understanding of how our surnames were taken/given. In this paper we investigate and deconstruct our Irish and Jewish ancestry. Fitzpatrick and Keesing are anglicised/normanised/colonised surnames that exemplify attempts to dis/member our identities. Here we re/member them, but with that comes a realisation that ‘everything has changed’ and with that come new dis/memberings and re/memberings.
