This article depicts everyday family genealogy as a vehicle for the sociological imagination that links personal biography to social–historical contexts across generations. As genealogists construct current from past identities, they engage a sociological imagination that potentially enables them to grasp how intersectionality – gender, race, ethnic, sexuality, nation, class, and age relations – is articulated through history. The key aims here are: (1) to provide background conditions behind the growth of genealogy; (2) to reveal how doing and studying family genealogy engages a sociological imagination that can be a vehicle for perceiving the intersectional underpinnings of social memories. Genealogy can be seen as a political practice where race‐class‐gender within social memories can contribute to diverse stories from new standpoints in American history.
