When formed in March of 1795, Brookfield was part of Herkimer County, and from 1798 through 1805, was part of Chenango County. It lies in the south-east corner of Madison County. The Unadilla river forms its eastern and southern boundaries. One of the earliest settlers was Captain Caleb Brown who built a saw mill at "Unadilla Forks." 
Early settlers, hailing from Rhode Island, included a fair number of Quakers among them.
Early villages included Leonardsville, Clarkville, and South Brookfield.
