Town History of Clarksburg MA
The first documented inhabitant of what would become the Town of Clarksburg was a Soldier from Fort Massachusetts named Seth Hudson (hence the Hudson Brook naming)in 1749, when he felled a tree just North of Natural Bridge). He was both a Soldier and Surgeon from Fort Massachusetts in the neighboring City of North Adams, who went on to later help found the neighboring Town of Pownal, Vermont.
Captain Matthew Ketchum, Colonel William Bullock, and Nicholas Clark are credited with having originally settled the eventual township in 1769, and the latter ultimately became Clarksburg's namesake due to the birth of a child, thus giving the Clarks one additional vote in the naming of the Town. The town began as a mostly agrarian community, with mills springing up along the waterways in the nineteenth century. The major mills were one to make cashmere, and several mills supplied gunpowder during the Civil War. However, the industry was stopped by the town after one of the mills exploded in 1869 in the area of what was "Sunnysides Lounge", and that section of Town was known for many years as "Powdermill Flats".
