The Gilman Family

The NH State Treasury moved to this house in 1775 and Nicholas Gilman Sr. served as State Treasurer during the Revolution when Exeter was the state capital. In subsequent years, two of his sons, John and Nathaniel, also served as State Treasurer.

Museum Today

Museum exhibits introduce visitors to 18th century Exeter when the town was a bustling, dynamic seaport, and home to the Ladd and Gilman families. Exhibits focus on Exeter as a Revolutionary War capital, the Gilman Family, roots of the American Revolution, NH’s role in the War, the founding of our Nation, the Society of the Cincinnati and our early years of local government with John Taylor Gilman, NH’s longest serving term Governor. Other areas of focus include New Hampshire’s role in the war and its militia, while the Northern Campaign of the Revolution is explored using prints, weaponry and military papers.
