The Homes series documents the management of four of John D. Rockefeller, Sr.'s and John D. Rockefeller, Jr.'s estates and their New York City homes. The estates are Ormond Beach, Florida; Lakewood, New Jersey; Pocantico Hills, New York; and Seal Harbor, Maine. The New York City homes are 4, 10, and 12 West 54th Street and the apartment at 740 Park Avenue. There is also information regarding John D. Rockefeller 3rd's apartment at One Beekman Place. Most of the material deals with property purchases, employees, the construction of homes, out buildings, and private roads, relations with neighbors and local communities, the contents of the houses (particularly art collections), and the general maintenance and operation of the various homes. The correspondence is between members of the family and the family office on the one hand, and estate managers, employees, contractors, real estate agents, neighbors, members of the various communities, and art dealers on the other.
