The collection primarily consists of the correspondence and papers of members of twelve different families in the Philadelphia area. A great deal of the correspondence relates to concern for health and relationships among family members. The papers are often concerned with matters of business as well as estates, both in terms of the exchange of property, but also as property and possessions of deceased family members. Many of the principals in the collection traveled for business or pleasure. As some of the families or family members were Quaker, issues such as attendance at meetings and the conduct of business are also discussed. There are some photographs and other images.
