Oyster River was part of Dover throughout its first century. The Plantation was granted rights as an independent parish in 1716 and incorporated as a township in 1732 when it was renamed Durham. Rev. Hugh Adams claimed to have proposed the name "Durham" in an address to the General Assembly in 1738. Two of the earliest settlers of Dover were William and Edward Hilton, the direct descendants of Sir William de Hilton, Lord of Hilton Castle in County Durham, England, but there is nothing to prove that Durham was named in their honor.
