The property now known as Duntryleague was part of one of the first land grants in the Orange area in 1834, located adjacent to the later gazetted township of Orange and comprising a full square mile. The property was grazed for many years by various owners and tenants, but William Sampson, the first grantee who was himself an absent land owner with interests in the Mudgee area, also established his early property called Campdale on the land. The property also included other early buildings important in the history of Orange such as John Peisley's the Coach and Horses which is regarded as the first inn in the Blackman's Swamp (Orange) area.
