In the 17th century, Nateley and Greywell manors were owned by the
Zouche family of Bramshill, then the
Henley family. The 876 acres of Greywell Manor were bought in 1787 by
Guy Carleton, 1st Baron Dorchester, former Governor General of Quebec. Trustees who purchased the Manor for Guy Carleton described it as "A delightful spot... charming hills much woods, good water, a small river in the bottom with good Trout... the Farm buildings in most excellent condition." There were three farms in the Manor, of which Grewell Farm was probably the least significant. An estate survey of 1788 shows the line of the tunnel for the
Basingstoke Canal which crosses the north of the estate. The farm was tenanted, Guy Carleton choosing to live at
Kempshott nearby and then in
Middlesex. He died in 1808 and it was not until around 1824 when the farm had become a gentleman's residence that
Arthur Henry Carleton, 2nd Lord Dorchester, finally moved in. The Greenwood map, 1826, indicates that a formal garden has been started and it is clear that a gentleman's residence would have had pleasure grounds as well. The Tithe map of 1842 shows a mansion, approach drive, stable block, grounds and a surrounding park. The 1st edition OS maps show a partly walled kitchen garden as well as lawns and features such as a fountain and a pond. An old chalk pit to the east of the approach drive has become The Dell. Footpaths lead through the park and there has been much planting of trees in the parkland. An article in the ''Gardeners' Chronicle'', 1907, indicates that the period 1870s – 1890s there was a great deal of planting both of plants and trees. A Dutch garden is described in what was originally the chalk pit (shown on early, old maps). The title of
Lord Dorchester became extinct in 1897, but Henrietta Anne Carleton (by then Mrs Leir-Carleton), daughter of the last Lord Dorchester, applied for reinstatement of the title, which was granted by
Queen Victoria in 1899. Henrietta then became the
1st Baroness Dorchester. In its turn, this title became extinct in 1963 when Henrietta's son from her first marriage to
Francis Paynton Pigott, died. However, their daughter had already married
William James Harris, 6th Earl of Malmesbury. In 2000, William James Harris died and James Carleton Harris became
7th Earl of Malmesbury thus a direct heir of
Guy Carleton, 1st Baron Dorchester. He is the current owner of Greywell Hill House. ==St Mary's Church==
