The collection documents the lives of the members of the Potter, Guererro, James, and Lord families from the 1850s to the 1940s, beginning with Henry Cardwell Potter (1822-1902), a Philadelphia businessman who through his business dealings became Consul of Nicaragua for the city. Potter's daughter married into the Guererro and James families; her daughter married into the Lord family. The bulk of the collections consists of correspondence; a large portion of these letters are addressed to Mary Agnes Guererro from her fiancé John Carlisle Lord, a professional ball player. The collection also contains a large amount of business materials, including papers relating to Potter's office as Consul, Dr. James' medical practice, and the sale of the family estate, La Hacienda Santa Enriqueta. A large scrapbook, maintained by Dr. James, contains newspaper clippings, correspondence, and programs of social events. The collection is supplemented by a large collection of photographs, some of which have been identified.
