Land Surveyor in Jamesport, Suffolk County, NY

Jamesport was first settled in the 1690s and was originally called “Aquebogue.” It was renamed “Lower Aquebogue” when another hamlet called “Upper Aquebogue” was established to the west. The Jamesport Meeting House, built in 1731, is the oldest operating church building in Suffolk County

“Jamesport” is named for James Tuthill, who settled with his family in the area south of Lower Aquebogue, on the Peconic Bay, in 1833. Over time, Lower Aquebogue came to be called Jamesport, while the community 1 mile (2 km) to the south, previously called Jamesport, came to be called South Jamesport (and is included in the present-day Jamesport CDP). Upper Aquebogue became Aquebogue.

James Tuthill tried to establish a commercial whaling and shipping wharf on the Peconic Bay, in what is now South Jamesport . But the effort was unsuccessful, because the water in the Bay at low tide was too shallow to accommodate ships. However, the Long Island Rail Road established service between Jamesport and New York City, after which Jamesport became a popular resort area, with several large bayfront hotels. These included the Miamogue Hotel and the Great Peconic Bay House, which operated until 1952. Jamesport also became a thriving fishing community, and was a center for scallop and bunker (menhaden) fisheries.
