In 1747 the colonial General Assembly designated this area an ecclesiastical society and named it Marlborough. In 1803 the Connecticut General Assembly incorporated Marlborough as a distinct town, deriving its lands from Colchester, Hebron, and Glastonbury. Sadler’s ordinary, believed to have been built about 1653 near Lake Terramuggus, entertained travelers on the Path to Monhege between the Thames and Connecticut Rivers. The first schoolhouse here was built in 1760, when farms and saw mills flourished. Marlborough Tavern, still serving the public, opened late in the colonial period. During the nineteenth century, the New London Turnpike spurred local industry, chiefly textiles, but that industry vanished when the last mill burned in 1907, leaving Marlborough mainly a residential community. Mary Hall of this town, an educator, became in 1882 the first woman lawyer admitted to practice at the bar of Connecticut.
