Easton (Etune) is mentioned in the Domesday Survey where it formed part of the domains of Roger, Earl of Montgomery. In the 12thc the village passed to the family of Costentine (or Constantine). In the 12thc, the church at Eaton Constantine was the chapel-of-ease to Leighton. Later it became a separate parish with its own rector. An incomplete list of rectors and chaplains goes back to 1225. The church was built in 1847-8 to replace smaller medieval building. (Information provided by explanatory panel in church.)
