The main territory in which the Oliver surname lived and exercised control was Jedforest, an indeterminate area situated south west and south of the Border town of Jedburgh. Originally the lands of Jedforest were held directly by the King, and as his "tenants in chief" the Olivers would have held their lands by "Crown charter", but after a number of changes in feudal superior, Jedforest was granted by the King to the Clan Douglas (the Red Douglas) under whose protection the Olivers subsequently lived.
