Founded in 1947, the press was originally named The Pequot Press, after a local Indian tribe. It was an adjunct to the Stonington Printing Company in Stonington, Connecticut. Twenty years later, in 1967, the new owner brought the still small publishing company down the coastline to Essex, Connecticut and styled it as a publisher to the historical societies and assisted neighboring towns and other local groups with their publishing requirements.
