In 1936, the MCHA expanded its mission to include the preservation of historic properties. In that year, the first of five historic properties came to the MCHA when Mrs. J. Amory Haskell purchased, restored and furnished Marlpit Hall (circa 1756) in Middletown, and then presented it to the organization. In 1959, the Holmes-Hendrickson House (circa 1754) was given to the MCHA by Bell Laboratories and moved two miles to its present site in Holmdel.
