Elias Abbott was born on October 24, 1757, in Concord, New Hampshire, to Reuben and Rhoda (Whittemore) Abbott. Raised during the formative years of the American colonies, he came of age just as the Revolutionary War broke out across New England.

During the Revolutionary War, Abbott served as a Private in the New Hampshire forces. His military service included duty under Captain James Osgood, Captain Peter Kimball, and Captain Benjamin Sias, within regiments commanded by Colonel Timothy Bedel, Colonel Thomas Stickney, and Colonel Enoch Dane. He participated in defense actions across the Northern Theater, including troop movements supporting New Hampshire’s frontier defenses and Continental Army operations.

Following his military service, Abbott settled in the area that was originally part of Canterbury, New Hampshire. In 1780, when Northfield was set off from Canterbury as its own town, Elias Abbott was among its early prominent residents. He served as a deacon in the local church community and lived out his civilian life as an active member of the town.

Deacon Elias Abbott died at the age of 87, placing his death around 1844 to 1845. His headstone, located in a historically unrecorded and overgrown burial site in the woods off Bean Hill Road in Northfield, explicitly honors his service with the inscription: “Deacon Elias Abbott, Died , aged 87 years, He was a soldier of the Revolution.”
