Originally a part of Rochester variously called the "Northeast Parish", "Three Ponds" or "Milton Mills", the town was settled in 1760. It was set off and incorporated in 1802 as "Milton", the name either a contraction of "mill town", or else derived from a relative of the Wentworthcolonial governors — William Fitzwilliam, Earl Fitzwilliam and Viscount Milton. The town of Fitzwilliam also bears his name. The high concentration of water powered industries in Milton caused Ira W. Jones to found and operate an engineering firm from offices on Main Street in Milton. The company did business as I W Jones Engineers. In 1893 Jonas Spaulding opened a leatherboard mill in Milton, organizing the business as J. Spaulding and Sons. His sons were Leon C., Huntley N. and Rolland H., of whom Huntley and Rolland would serve as governors of New Hampshire. Jonas and his sons would undertake the construction of another leatherboard mill in North Rochester around 1900. Jonas died before the North Rochester mill became operational. The brothers continued to run the business successfully and brought the Spaulding Brothers leatherboard mill in Townsend Harbor, Massachusetts, under the J. Spaulding and Sons banner in 1902. They were successful with a machine to manufacture shoe counters and with experiments to make vulcanized fibre. In 1912 they opened a purpose-built facility to make vulcanized fibre in Tonawanda, New York. In 1913 J. Spaulding and Sons opened a second leatherboard mill in Milton. They also acquired the Kennebunk Manufacturing Company, which made lunch boxes and violin cases using leatherboard and vulcanized fibre and at one time had facilities in Milton as well. The town contains some distinctive architecture, particularly the Milton Town House, built in 1808, and the Milton Free Public Library, a Second Empire former schoolhouse built at Milton Mills in 1875.

The Milton Free Public Library in Milton Mills is housed in a building that was constructed in 1875 as a school house, and continued in this role until 1991, when its elementary grade students were bused daily down to Milton. It was the following year — 1992 — that MFPL relocated from smaller premises on Jug Hill Road to its current location. Before that the library was located at the current historical society, which was built in 1916 with the purpose of becoming a library. The land was donated by John E. Towsend, and did not become part of the town until September 26, 1921. The very first librarian that worked at this location was John Simes, and the first group of trustees were John E. Horne, Everett Fox, and Moses G. Chamberlain.
