Native Americans liveD HERE before European settlers arrived

Native Americans, probably Pennacook indians, had a summer camp site on Weir Hill, North Andover on a lake they called Cochichawick ("great water".)  However, by the time Andover was founded in 1645 European diseases and inter-tribal wars during the French and Indian wars had decimated the population. The first European settlers had permission from the Massachusetts Bay Colony to settle the plantation. However, they also took the precaution of paying a local Indian sagamore Cutshamache "six pounds of currency and a coat" for the rights to the land subject to the condition that Roger, a local Pennacook man, would be allowed to plant his corn and take alewives from a local water source, now called Roger's Brook.
