History
Grafton was one of the five counties originally identified for New Hampshire in 1769. It was named for Augustus FitzRoy, 3rd Duke of Grafton, who had been a supporter of American causes in Parliament, and who was serving as British Prime Minister at the time. The county was organized at Haverhill in 1771, and originally included the entire northern frontier of New Hampshire, including several towns now in Vermont. In 1803, the northern area was removed for the formation of Coos County. The three counties to the south were Strafford, Hillsborough and Cheshire, and the eastern edge bordered the "District of Maine". In 1797, the county had 50 townships, 17 locations, and a population of 23,093.
