The historic significance of Fenwick is defined by both its two-century long association with the Jones, Fenwick, and White families, and by its transitional Federal/Greek Revival style façade. Benjamin Jones, who owned the farm where the structure was built from 1827 to 1844, is one of the prominent names in the history of the Pine Barrens bog iron industry and owned the Hanover Furnace. James Fenwick purchased the site in 1844 and was an early innovator in cranberry culture. He expanded his operations in 1857 by acquiring 108 acres of natural bogs in the Pinelands near Fenwick Manor.
