Merrimack is a sprawling bedroom community, located between Nashua and Manchester, the two largest cities in the state. The town is home to about 23,000 people, with residential subdivisions mixed with some commercial development and a rural feel remaining in some of the lightly populated residential areas. The Merrimack River is the towns eastern border, the Souhegan River runs through the middle of the town, and Naticook Lake is a popular recreation spot in the southern part of town.
Although first occupied in 1665, settlement did not begin until 1722, when the establishment of Brenton’s Farm (Litchfield) presented the need of a ferry across the river to reach new settlements. The ferry concession was owned by Edward Lutwyche. When the town was separated from Nashua (then Dunstable) in 1746, it was given the name of the river, Merrimack.
