DNA Testing and Identities in Family History Research

Abstract

In the preceding decades, rapid technological advancements and increasing democratisation of historical records have been coupled with scientific data from DNA testing, which has revolutionised the family history industry. Going beyond the traditional archives and databases, DNA profiles present nuanced confirmations, puzzles, and contradictions generated through this biological lens. Family history researchers seek iterative engagements with their familial pasts and, in the process, amplify their contemporary identities. This specialised group of historians illuminates their families’ travels through the broader historical landscape, constructing micro-narratives using a broad range of investigative modalities. This article reports on the findings of a large international study (n = 1016) that investigated family history researchers’ motivations for undertaking DNA testing, their experiences, and its impact on their perceptions of individual, national, and global identities using Berzonsky’s socio-cultural model of identity construction (2003, 2011) as an analytic frame. Using a survey methodology, it was concluded that DNA testing can expand and disrupt long-held notions of identity and has the power to shift perceptions and understandings of the self while simultaneously providing a new era of opportunity to reconceptualise national and international affiliations. It suggests further investigative avenues to assess the potential of DNA testing, which may promote social cohesion, inclusiveness, and global citizenship.
