In 1822, Deacon Charles Lee acquired the rights to erect a cotton mill on the east side of what is now Bridge Street in Willimantic. The mill was acquired in 1845 by two men from Rhode Island, Amos and James Smith, who renamed it the Smithville Manufacturing Company. In 1828, three men from Rhode Island, Mathew Watson, and Nathan and Arunah Tingley, erected another cotton mill, called the Windham Manufacturing Company, on the west side of Bridge Street. The Smithville and Windham mills, on either side of Bridge Street, would merge in 1907. The company would later be named the Quidnik-Windham Manufacturing Company. The stone mill buildings do not survive today, but some of the worker housing and a former company store, remain standing. An assessor’s record dates the store to c. 1850, although it may have been constructed in the 1820s by Deacon Lee himself. It may also have been the Windham Manufacturing Company store that was owned by George M. Harrington from 1874 to 1883. Located at 24 Bridge Street, the store is built of ashlar granite, with alternating courses of wide and narrow stone. The south gable-end of the building has large loading bay windows facing the adjacent railroad tracks.
