History

Henry County was formed on January 13, 1825, out of Fulton County, Illinois. It is named for Patrick Henry, Revolutionary War firebrand and champion of individual rights, to whom the slogan "give me liberty, or give me death" is attributed. The county was settled by people from New England and western New York, descendants of English Puritans who settled New England in the colonial era. The New England settlers founded the five towns of Andover, Wethersfield, Geneseo, Morristown and La Grange.

The settlement of Cambridge came about in 1843, when the owner of the land in that area (Rev. Ithamar Pillsbury) dedicated a section of his properties to a town council; lots were sold to incoming settlers, and construction of the town proper began on June 9, 1843. The incoming "Yankee" settlers made Henry County culturally similar to early New England culture.
