The papers of the Bonsall Family of Pennsylvania primarily consist of correspondence, personal and professional documents, journals, genealogical tables, photographs, and a family Bible. The majority of the letters, documents, and journals were generated by or for Edward H. Bonsall (1794-1879) and the members of his immediate family, particularly his eldest son, Spencer Bonsall (1816-1888). Also included are documents produced by or for other Bonsall family members, from Richard Bonsall who settled in Philadelphia with William Penn (ca. 1683) to Eleanor Crosby Martin Bonsall (1894-?), the daughter of William Martin Bonsall and granddaughter of Spencer Bonsall.
