Genealogy is everywhere– online, on screens, through organizations and conferences and more. But technologies aside, genealogy was everywhere in the 1700s, too. And while we may think of Americans living in the 1700s as largely the subject of genealogy research, they were active participants in what was a foundational interest and practice in their own time. Family histories were deeply meaningful for diverse early Americans, but it was also baked into the very structures of their society through law, politics, and religion. From deep research across 18th-century British America, Karin Wulf’s new book, Lineage: Genealogy and the Power of Connection in Early America, examines how we can understand the role of genealogy then, and its impact now.
