Andover is named for the Connecticut town, which in turn was named for the one in Massachusetts.  The town was nearly twice its present size when it was granted October 13, 1761.  However, a ridge of highlands (including the aptly named Terrible Mountain) made it virtually impossible to get from one side of the town to  the other, so the western portion was made into the separate town of Weston in 1799.  Ironically, most of the Pease family, for whom the Andover village of Peaseville was named, found themselves in Weston after the split.  Today Andover is home to many artisans, small farms and even a hot air balloon maker!
