The first patent of land was issued to Ezekiel Benson, a land surveyor, on August 7, 1820. That was followed by land issued to Alan Robinet in 1822. In 1863, Orangeville was named after Orange Lawrence, a businessman born in Connecticut in 1796 who owned several mills in the village. As a young man, he moved to Canada and settled in Halton County. During Mackenzie's rebellion in 1837, he was a captain in the militia. Lawrence purchased the land that became Orangeville from Robert Hughson. He settled in the area in 1844 and established a mille. The post office dates from 1851. Orange Lawrence committed suicide December 15, 1861. In 1873, the Act of Incorporation was passed and Orangeville was given town status on January 1, 1874. The public library, located at Broadway and Mill Street, was completed in 1908. Andrew Carnegie, well-known businessman and philanthropist, provided financial assistance for its construction.
