History:
The mountains here perpetuate the names of New Hampshire's most legendary Indians;
Passaconaway (Child of the Bear) was a peace-loving chief who, in 1627, united over 17 Indian tribes of Central New England into the Panacook Confederacy. As the first "Sagamon," he ruled wisely until his death in 1669.
Kancamagus (The Fearless One), grandson of Passaconaway, succeeded his uncle, Wonalancet, around 1684 as third and final Sagamon of the Penacook Confederacy. Kancamagus tried to keep peace between the Indians and the pioneering whites, until aggravated English harassments brought war and bloodshed. The confederacy's tribes scattered after 1691, and Kancamagus and his followers moved north to upper New Hampshire or into Canada.
About 1725, Paugus (The Oak), was Chief of the Pequawket Tribe along the Saco River. Later, around 1760, Chocorua, brave and perhaps a chief of the Ossipee Tribe, lived near today's Conway or Albany. Legends agree that Chocorua died on the summit of the mountain which now bears his name.
