Part of the Forest of Bowland, the historic township had two divisions—Lower and Upper Easington—which are geographically non-contiguous. Mystery surrounds the origin of these two divisions. From Norman times, Lower Easington formed part of the Liberty of Bowland, being a possession of the Lords of Bowland. Its manor was subinfeuded and by the thirteenth century was held by the De Wannervill family. Ownership passed to the Bannister family in the early sixteenth century, with the manor eventually being broken up and sold off piecemeal in the 1690s. The manor sat due south of Slaidburn within the modern-day township of Newton-in-Bowland. Upper Easington is the larger of the two divisions and includes Dalehead and Stocks Reservoir. It abuts Gisburn Forest and marks the easternmost extent of ancient Bowland. To the north of Upper Easington sits the Cross o'Greet, the ancient boundary point and watershed between the medieval lordships of Bowland and Burton-in-Lonsdale, Clitheroe and Hornby; the route up to the Cross across what was anciently called "Gradale" is perhaps one of the most ruggedly beautiful in the Forest. It is thought that the lands of Upper Easington may originally have been part of the Slaidburn township but grants by the de Lacys to Kirkstall Abbey in the twelfth and thirteenth centuries gave the area its own distinctive identity. The township of Rushton was granted by Robert de Lacy, 3rd Lord of Bowland, in 1180. This was to be the site of the area's monastic grange. In 1220 or thereabouts, John de Lacy, 5th Lord of Bowland, granted an area west of the Hodder and north of Rushton known as "Gamellesarges". In Helen Wallbank's unpublished translation from the Latin, the description of Upper Easington from the grant of 1232–40 reads: Gradalehals is the 'grey dale' at the head of Cross o'Greet; Kesedene is Keasden Brook; Rowenumcnothes is Bowland Knotts; Hesbrithehawebroc is Hesberts Hill Brook ; Thirnesetegilebroc is now known as Bottoms Beck, but was formerly known as Bridge House Beck, all these becks being names for the same beck at different locations. For three centuries, Upper Easington remained Kirkstall Abbey's most westerly land holding before being forfeited by the Abbey in 1539. After the Reformation, Rushton Grange was acquired by the Braddyll family of Whalley and thereafter by the Johnson and Wiglesworth families. The Wiglesworths later built their imposing mansion, Townhead, in Slaidburn. Charles Towneley, 13th Lord of Bowland, acquired the grange in 1860 before its eventual sale to the Fylde Reservoir Company. The mesne manor of Hammerton also lay within Upper Easington until the time of the Reformation when the Hammerton family lands were confiscated by the Crown. The manor was later held by the Greenacres and Breres families. Historians continue to puzzle over the existence of two Easingtons. The Coucher Book of Kirkstall Abbey suggests the lands of the upper Hodder north of Slaidburn were not known as Easington in the thirteenth century, merely as "Bouland". We might speculate that the manor of Lower Easington gained some influence over the area after the Reformation, with the civil administrative map being redrawn to reflect this change, perhaps during the seventeenth century. However, the evidence for this is slight, although a junior branch of the Bannister family was present at Newhouse, south of Catlow, from the early 1600s. In 2009, a rare limeburners' clamp kiln was excavated at Halsteads in Upper Easington which carbon dating suggests was last fired somewhere between 1205 and 1280. This approximates to the period in the thirteenth century when John de Lacy, 5th Lord of Bowland, gifted his lands to Kirkstall. There is evidence of prehistoric settlement in Lower Easington: with Skelshaw Ring, a Bronze Age monument, lying due south of Slaidburn.
