History
The area along the Naugatuck River, comprising the present Elm Street section of Ansonia and Derby Avenue section of Derby, was first settled by English colonists in 1652; it was originally a part of the township of Derby. Early settlers developed subsistence farming, and used the river for sawmills and gristmills.
In 1844, Anson Green Phelps (1781–1853), a merchant and philanthropist, wanted to expand the old borough of Birmingham (the present downtown of the city of Derby) to the north along the west side of the Naugatuck River to enable industrial development. Unable to purchase the land from its owner, in 1844 Phelps acquired land along the east side of the river; today this is Ansonia's downtown section. A canal was dug for river power to drive the factories and businesses in the new industrial village, which Phelps named "Ansonia". He wanted to name the industrial village as "Phelpsville", but learned there was another village in the region by that name. As suggested by a friend, Phelps used his first name as a root instead, resulting in "Ansonia".
