Monmouth County Historical Association
The Monmouth County Historical Association was established in 1898 by a group of county residents headed by professional educator Caroline Gallup Reed. They soon incorporated in order “to discover, procure, preserve and perpetuate whatever relates to the history of Monmouth County.” In 1931, the present Museum and Library, a brick Georgian-style building designed by architect J. Hallam Conover, was constructed in Freehold, the county seat of Monmouth County, New Jersey. The enthusiasm generated by the announcement of a new headquarters brought in numerous contributions of furniture, artifacts, paintings, rare documents and books. Historic properties  

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. During the 1960s, the MCHA acquired and restored two more of Monmouth County's most historically significant buildings. In 1966, the Covenhoven House (circa 1752) in Freehold, which served as British General Sir Henry Clinton's headquarters before the Battle of Monmouth, was acquired; and in 1968, the Allen House (circa 1705) in Shrewsbury, which is interpreted to reflect its late 18th-century use as a tavern, became an MCHA property. These four historic properties, furnished with the MCHA's decorative arts collections to reflect life in the 18th century, are open to the public seasonally as historic house museums. In 1999, the MCHA acquired an important example of the Victorian style, the Taylor-Butler House (circa 1853), built by later generations of the Taylor family of Marlpit Hall, which is on the adjoining property. Education 
The Monmouth County Historical Association is recognized as one of the country's leading local history organizations and remains committed to making its museum and research collections accessible to the public through publication, educational programs, outreach activities and an annual changing and permanent exhibition program. The MCHA's main Museum and Library building in Freehold, New Jersey is open throughout the year and its historic sites are open seasonally from May through September. Nearly 8,000 school children participate in school programs each year presented at the museum, the historic houses and in outreach programs given in classrooms throughout the area. Publications
