Coos County History

Coos County was separated from the northern part of Grafton County, New Hampshire and organized at Berlin December 24, 1803, although the county seat was later moved to Lancaster, with an additional shire town at Colebrook. The name Coos derives from the Algonquian word meaning "small pines".
