About Cranbury Township, NJ

A deed for a sale of land and improvements dated March 1, 1698, is the earliest evidence of buildings constructed in present-day Cranbury. A home in Cranbury was used by Alexander Hamilton and the Marquis de Lafayette as a headquarters during the American Revolutionary War, and they were visited by General George Washington on June 26, 1778. As part of orders issued during the Presidency of George Washington, maps of Cranbury were made showing the presence of a church, a mill and 25 other buildings. During its earliest years, the location was usually spelled as "Cranberry". Rev. Joseph G. Symmes argued in 1857 that the name was spelled improperly and that the suffix "bury" was more appropriate, leading the name of the community and brook to be changed to "Cranbury" in 1869. The name has been attributed to wild cranberries that grew in the area.
