A charter dating from 990 relates to the manor of South Stoneham, and archaeological evidence of a Saxon settlement was found during building works in the area immediately around the current South Stoneham House. The manor of South Stoneham was originally called Bishop's Stoneham, and was held by the
Bishop of Winchester at the time of the
Domesday Book. Other than
St. Mary's Church (which is close to South Stoneham House but predates it considerably) and a few adjacent houses, there was no village of "South Stoneham"; instead these adjoined, as it does today, Swaythling ("now practically a suburb of Southampton, and [a] favourite residential quarter"), which became the generally used name for all the rest of the parish. The tenants of the manor apparently took their name from it; a Gregory de South Stoneham (or Gegory de Stoneham) is recorded there in 1236 and 1249, and in 1315 the manor was held by Nicholas de South Stoneham (son of Guy de South Stoneham). In 1348 Thomas de Stoneham and his wife Alice were lord and lady of the manor, and five heiresses of theirs – possibly daughters – held the manor in 1367. However, that year they
quitclaimed it to Adam le Chaundle. Capelyn sold the manor to William Conway in 1600, who sold it to Edmund Clerke in 1612; Clerke's son inherited the manor in 1634 but only survived for a further two years, at which point the manor passed to Edmund Clerke's 8½-year-old grandson, another Edmund. This Edmund Clerke was the
Sheriff of
Hampshire and clerk to the Signet in 1671. South Stoneham House was constructed in 1708 as the Dummers' family home, and has been attributed to
Nicholas Hawksmoor. Dummer was from nearby North Stoneham and had been baptised in
St. Nicolas' Church there. As of 1915 the grounds of the house comprised 110 acres, with 5 acres of water, and were laid out after 1722 by
Capability Brown (though very little of the original landscaping remains). Edmund Dummer was declared bankrupt in 1711 and he died in debtors' prison two years later. His cousin Thomas, a lawyer who had acquired the manor on Edmund's behalf, fought a lawsuit attempting to gain control of the property; however in 1716, Edward Nicholas of
Newton Valence took ownership of South Stoneham. William Sloane, whose brother founded the
British Museum, purchased the manor from Nicholas in 1740, "Gascon's Meadow with house thereon in South Stoneham" was
reconveyanced the next year. In 1888 South Stoneham House was purchased from Davison by
Samuel Montagu, 1st Baron Swaythling. ==Parish==
