Founding Soon after the establishment of a village in the
Huntington area,
English settlers sought to further expand their territory.
Larkfield and Clay Pitts Two distinct communities formed in the area now known as East Northport. The more populous settlement known as Larkfield was located on the northern side, near Vernon Valley (now part of
Northport). Larkfield originally developed near the location of Genola Cemetery, just north of the modern-day junction of Larkfield Road, Vernon Valley Road, and Laurel Road. A second community located on the southern side was known as Clay Pitts, named for its vast deposits of red
clay. This clay, which had been used by Native Americans to form pottery, was used by the Europeans to form
bricks for construction. The land between Larkfield and Clay Pitts was well suited for agriculture, and the region prospered in the late 18th century as a thriving farming community by supplying produce to markets in
New York City and
Brooklyn. However, just a few years later the LIRR decided to move the
Northport station to a new location in Larkfield to facilitate further railway extension to
Port Jefferson. The new railway station located at Larkfield Road and Bellerose Avenue opened on January 13, 1873. Although the station retained the name of Northport, train conductors would refer to it as "East of Northport", because the station was located east of the
railway junction which used to direct trains north to the old station located in the Village of Northport. Despite the fact that East Northport is primarily
south of Northport, the area became known thereafter as East Northport. In 1998, East Northport's
United States Post Office building was renamed the Jerome Anthony Ambro, Jr. Post Office Building through a bill passed by the
United States Congress, in honor of
the former congressman for
New York's Third congressional district. As of 2025, East Northport is the largest community in the town of
Huntington, by land area, and third in population behind
Huntington Station and
Dix Hills. ==Geography==
