Orielton estate was amalgamated with the neighbouring Wivenhoe. In 1847 it was purchased by Camden miller, John Perry who had been using its mill and occupying Orielton before purchase. Perry was growing cereals and milling them for flour. Agriculture continued with cereal crops and livestock grazing. Perry later subdivided a portion of the estate and leased the main property to Charles Thompson, Clerk of the Bench to Camden Court. During the whole of this early period the estate seems to have been used mainly for grazing, with some limited agriculture. Ownership, 1861 to 1876 In 1861 William Peisley, a carcass butcher bought Orielton. From 1861 until 1864 when Peisley put it up for auction and it was bought by (Sydney) absentee owner, "gentleman" John Thomas Neile. Neile bought the estate in two parcels - the Home Farm (in 1864, of ), in cultivation; and a second farm on the other (eastern) side of the "Great South" (now The Northern) Road, of with a farm house and stockyard. The Mill (recently built by previous owner Perry, the miller "on the best position in the district" and in of paddocks, was passed in at auction. Neile then bought it for A£600 - a knock-down price for so elaborate a structure. He maintained the whole property as a going concern until 1876. It featured extensive cleared and fenced paddocks, paling-fenced orchard and picking garden adjacent to the west side of the house, extensive buildings/quarters set on a knoll above the alluvial flats and below the ridge line, extensive trees and shrubs to the east or front entry, probably cypress, Bunya or hoop pines and other broad-canopied trees, a three-storey mill, livestock shelters and paddocks, ploughed paddocks and a cottage fronting the Northern Road's eastern side farm. In 1863 Abraham Davy of Harrington Park purchased Lot 1 of Orielton Farm () from three Sydney businessmen who had earlier purchased the estate - John Lait of Sydney, James Ryan of Emu Plains and James Jones of Sydney. An auction notice in 1864 describes Orielton's extensive development. It was sold to Neile, who bought a major homestead with infrastructure. A (likely 1865) photograph from the summit of the hill to the west, shows a well-kept farm complex in an ordered estate. The Peisley family came to be regarded as local gentry and some family members remained prominent in the district after they left Orielton in 1876.
