<i>A Huguenot on the Hackensack</i> explores the life and legacy of David Demarest, a seventeenth-century French Protestant who, in middle age, emigrated to New Amsterdam and became one of the earliest settlers of the Hackensack Valley. There he founded a prosperous family that for nearly three centuries retained local influence and high status before being eclipsed by post–World War II economic and demographic changes. Transcending the narrow genealogical antiquarianism and filial pietism of traditional family history, the authors carefully set Demarest and his descendants in the context of their times.
