At the time of the Conquest, Hethe was held by the thegn Wulfward the White, who also held Finmere nearby. By 1086, assessed at 8 hides, it belonged to Geoffrey, Bishop of Coutances, whose tenant at Hethe was a certain Roger. By the early 12thc. the manor appears to be the property of the wife of Geoffrey de Clinton, Henry I's chamberlain, of Cassington and Glympton, Oxfordshire. She gave the whole village as a marriage portion to her daughter Lesceline, wife of Norman de Verdun. A church was in existence during the lifetime of Norman de Verdun, who died in 1154, and it was given by his widow to the priory of Augustinian canons at Kenilworth, founded by her father in 1122.
Originally the church was dedicated to St Edmund, but around 1300 on St George’s Day, it was rededicated to St Edmund and St George (VCH).
Hethe belongs to the Shelswell benefice, comprising Cottisford, Finmere, Fringford, Goddington, Hardwick, Hethe, Mixbury, Newton Purcell, Stoke Lyne and Stratton Audley.
