Some early Exeter settlers came from Hingham, Massachusetts, including the Gilman, Folsom and Leavitt families.[4][5] In 1647, Edward Gilman, Jr. established the first sawmill, and by 1651 Gilman had his own 50-ton sloop with which to conduct his burgeoning business in lumber, staves and masts. Although he was lost at sea in 1653 while traveling to England to purchase equipment for his mills,[6] his family later became prominent as lumbermen, shipbuilders, merchants and statesmen.[7][8]

The Gilman Garrison House, a National Historic Landmark, and the American Independence Museum were both former homes of the Gilman family.[9][10] The Gilman family also donated the land on which Phillips Exeter Academy stands, including the Academy's original Yard, the oldest part of campus.[11] The Gilmans of Exeter also furnished America with one of its founding fathers, Nicholas Gilman, and the state of New Hampshire with treasurers, a governor, representatives to the General Assembly and judges to the General Court.[12][13]

The Gilman family began trading as far as the West Indies with ships they owned out of Portsmouth. It was a high-stakes business. In an 1803 voyage, for instance, the 180-ton clipper 'Oliver Peabody,' owned by Gov. John Taylor Gilman, Oliver Peabody, Col. Gilman Leavitt and others, was boarded by brigs belonging to the Royal Navy under command of Admiral Horatio Nelson. Enforcing a blockade against the French, Nelson offered ship Captain Stephen Gilman of Exeter a glass of wine and paid him for his cargo in Spanish dollars.[14] The trip demonstrates how far afield the ambitious merchants of Exeter reached in their trading forays.
