Jean Kane Foulke du Pont (1891-1985) was a suffragette, prison reform activist, philanthropist, and wife of E. Paul du Pont (1887-1950). The collection contains three photocopied volumes of her ancestry of many of the earliest families of New Netherland and colonial Pennsylvania. The volumes include an introduction, genealogy tables, reproductions of paintings and photographs, and family lore collected by the author over the preceding sixty-eight years. There is an index at the end of volume three.
