History and development
The town was established in the early 18th century (incorporated in 1708) and grew in the 19th century as waterpower was harnessed for textile and other mills. The presence of rivers and rail lines encouraged mills, commercial streets and the rise of boroughs such as Danielson, which became local service and trading centers.
