Gill is a town in Franklin County, Massachusetts, United States. The population was 1,500 at the 2010 census. It is part of the Springfield, Massachusetts Metropolitan Statistical Area. The campus of Northfield Mount Hermon School is located in the Mount Hermon section of the town.
Prior to the arrival of English colonists, the Massachusetts portion of the Connecticut River valley was occupied by the Nipmuc, an Algonquin-speaking tribe. A site on the river near the great falls shows evidence of human habitation dating back 10,000 years or more. In the 1670s the Nipmuc had a village called Peskeompscut in that area. During King Philip's War in 1676, Captain William Turner led 150 colonists in an attack on this settlement, in which several hundred Indians (mostly women, children, and elderly) were slain. The falls came to be known as Turners Falls after Turner, who was slain in the battle. (The falls thereafter gave that name to the village of Turners Falls in neighboring Montague.)
Gill was first settled in 1776 and was officially incorporated in 1793. The town is named in honor of Moses Gill, a member of Massachusetts' Executive Council who became lieutenant governor in 1794 and acting governor in 1799 when Governor Increase Sumner died.
The first town meeting was held December 18, 1793, with Moses Bascom as moderator. Elected officers were Moses Bascom Jr. as town clerk and treasurer, Moses Bascom, William Smalley and Noah Munn as selectmen and assessors, and David Squires as constable.
