The Domesday book of 1086 refers to Moretune. Its meaning is not entirely clear but four of the five manor houses are identifiable. Saunderville is still called The Manor. It is a moated manor house with horses grazing in the railed paddocks, seen to advantage from the railway. Huse or Bray is a recently renovated low building nearby, with a paddock in front, at the T-junction at the east end of the village. The only trace of Adresham is the terrace on which it once stood, opposite the village school. There is a 1950s house on the site. Fulscot is west of the village, and is still a farm. At the time of the South Moreton Inclosure Act, 1818 c.18, the main landlord was Henry Hucks Gibbs, 1st Baron Aldenham and many of the inclosures were allotted to him. Later in the century a London butcher called Hedges used Rich's Sidings of the new Great Western Railway west by Didcot railway station, to supply much of the London meat trade. Hedges amassed a fortune and much local land, including the inclosures at Hall Farm and Fulscot Manor, both of which are still owned and farmed by his descendants.
Churches
The Church of England parish church of Saint John the Baptist at Bethesda, with its possibly Saxon doorway, stands by ancient earthworks at the southwestern edge of the village, by a ford on the former pilgrim route from the Downs to Dorchester. The church holds services only on major feast days and a few other occasions. Weddings, funerals and baptisms are also held by arrangement. The parish is part of the Churn Benefice, along with the neighbouring parishes of North Moreton, Aston Tirrold, Aston Upthorpe, Blewbury, Hagbourne, and Upton. South Moreton has a Strict Baptist chapel which has three services a week.
Character and amenities
There are a few large old houses on the High Street, some newer cottages at the east of the village, modern social housing to the West, and some 17th-century cottages between, many thatched. The largest house in South Moreton is The Hall, very close to the Huse. It is the last working farm in the village. Much Victorian history of the village is recorded in The Rector's Book, handwritten around 1905 from memories extending to 1845. It now deposited in the Berkshire County Archives at Reading.
Amenities
South Moreton has a school but no shop or village hall. Both Moreton Cricket Club and the North & South Moreton Women's Institute are both based in North Moreton.
School
South Moreton School, 200 yards east of Gothic Lodge on the High Street, is a County Primary School.
Transport

Former pub
The Crown Inn is in High Street. It was closed for some years around 1990, but re-opened as the last pub to be rebuilt by Wadworth Brewery before the implementation of statutory limits on breweries owning public houses. It declined in the 2000s and ceased trading in 2011. It re-opened again on 21 September 2012 but ceased trading again in July 2016. The pub reopened as a Community-owned pub in May 2019.
