Following the Third Anglo-Powhatan War, the General Assembly began setting up Forts along York River and its tributaries (which are known now as the Pamunkey and Mattaponi Rivers). Captain Roger Marshall was to manage Fort Royal (also known as Rickahock), for three years. After fulfilling the requirements he was granted a patent for the 600 acres of Rickahock (including Fort Royal and any buildings within), on March 14, 1649. That same day he sold these 600 acres of Rickahock to General Manwarring Hammond. These 600 acres brought Gen. Hammond's total landholding patents to 3760 acres on the south side of York River.
