Providing a glimpse in to the private life of a genteel lady in the early republic, the Elizabeth Bordley Gibson Papers consist of over 200 letters and notes written during the years 1795 to 1863. The bulk of the letters cover the period 1848-1863, and involve Gibson's correspondence with members of her extended family. Elizabeth was related to the influential Bordley, Mifflin, and Shippen families, three of the more prominent families in colonial and early republic Pennsylvania and Maryland. Most of the correspondence in the collection comprises letters between Elizabeth Bordley Gibson and her cousin Edward Shippen and her nieces Elizabeth Mifflin, Anne C. Ross, and Elizabeth Stump. Complementing other early American history collections at APS, the Gibson Papers offers important insights in to women's history and the history of influential mid-Atlantic families in nineteenth-century America.
