Abraham Dupont (1572-1640) was the progenitor of the South Carolina branch of the Du Pont family. In France, he dealt in manufactures of brass and copper. This is a small collection of his papers and those of his immediate descendants. The documents include the earliest records still extant in the Du Pont family papers. They are important for the evidence of descent they offer and for details about the ancestors of Pierre Samuel du Pont de Nemours (1739-1817). Many relate to landed property in Rouen and in the nearby parishes of Fontaine-sous-Préaux and Roncherolles.
