The Smith-Cadbury Mansion is significant both because of its association with several of Moorestown's pioneering families and because it represents three early periods of design and braced-frame construction. The building should be known as either the Hogsett or HainesHumphries-Smith House because its earliest section was built between 1730 and 17 38 by either its first owner, Francis Hogsett, or his successor Nehemiah Haines. This now constitutes approximately the eastern two-thirds of the central portion of the house. It consisted of a hall-kitchen and parlor, each with a corner fireplace, and perhaps two rooms on the second floor.
In 1738, Haines sold the house to Joshua Humphries, a carpenter, who undoubtedly made alterations to it shortly thereafter. These consisted of an enlargement to the west and removal of the corner fireplace in the hall-kitchen. Both rooms were enlarged, the parlor by moving the partition between the two to the west, and the hall-kitchen by the addition, which included a large kitchen fireplace, and, probably, a bake oven along the east wall. Paneling from this period survives in the chamber above the former parlor, now a dining room.
In 1766, Humphries sold the house to Samuel Smith, whose family occupied it until 1798. Smith was responsible for a large addition to the east, which almost doubled the size of the house. This contains a "new Parlor" with an 18th-century paneled fireplace wall, and a stair hall across the north front, which retains its original staircase.
During the first three-quarters of the 19th century, the house was owned by members of the Harris and Haines families. Several alterations were made during this period, including the addition of some of the porches and changes to the interior door and window trim. The most interesting of these was the insertion of an iron oven and tub in the kitchen fireplace.
In 1921, the property was acquired by a member of the Cadbury family. In almost half a century of ownership, the Cadburys made many changes, including the addition of several bathrooms and kitchens to make apartments. The Historical Society of Moorestown purchased the house in 1910 and operates it as a museum.
