The mission of the Lower Makefield Historical Society (Bucks County, Pennsylvania) is to stimulate an appreciation of the beauty and historic significance of Lower Makefield Township; to promote, research and publish findings regarding local history and culture; to establish a historical library and collections of artifacts; and to foster an interest in and encourage the preservation of historic buildings, sites, and landscapes in Lower Makefield and the greater Bucks County area. The Society's archival holdings span about 10 linear feet of materials, consisting principally of: research files on the Township compiled by Ralph N. Thompson; oral histories, house histories, and scrapbooks; and records of the Joseph Heacock Company, a nusery and dairy farm (1887-1930). The Society's oldest document is a 1729 deed; the most recent archival items date from the early 21st century. The Society also holds published books and objects, including a wooden model of the Octagonal School House once located in the township.
