Town of Clarence, NY Website
Since its establishment, Clarence has progressed from an isolated, heavily forested wilderness inhabited by a few sturdy pioneers to a thriving suburban town. Named from the English House of Clarence, the Town was established as the first township in Erie County on March 11, 1808. It contains more than 52 square miles and, while it has not incorporated villages, it is comprised of communities of Clarence, Harris Hill, Clarence Center, and Wolcottsburg as well as parts of the hamlets of Swormville, East Amherst and Millersport.
