The first English settler in what is today known as East Windsor, was William Pynchon, the founder of Springfield, Massachusetts.Pynchon selected the site of Warehouse Point because of its location near the Enfield Falls—the first major falls in the Connecticut River, the head of navigation where seagoing vessels were forced to terminate their voyages and transship to smaller shallops.Settlers avoided the East Side of the river due to the Podunk tribe who inhabited the area, particularly following King Philip's War in 1675.In 1818, resident Solomon Ellsworth Jr, was blasting a hole for a well alongside his house in town.These bones would later be sent to Yale University and eventually be identified as Dinosaur fossils, specifically one of an Anchisaurus.The bones are still at Yale and the Ellsworth Homestead still stands on Rye Street near the South Windsor line.The oldest section of town is Warehouse Point, which, as mentioned, was first used by William Pynchon in the 1630s, and later settled as part of Springfield in the 1680s.The Windsorville section of town was once its own community, featuring a church, post office, mini-mart, and a park.The new volunteer fire department building and senior center was built on the same site of the old town hall.Merchants on both sides of the river shipped timber products, brick, livestock, wheat, tobacco and other produce to supply plantations in the West Indies, importing sugar, molasses, salt, and British manufactured textiles, ceramics, hardware and glass on return trips.East Windsor Elementary School System serves students in pre-kindergarten through grade four.
