The place name derives from a local stream that was once known as the Oke and the addition of 'hill' to the name is descriptive of the site, as can be seen when approaching from the north. Various spellings of the name continue to be used.
The ecclesiastical parish was only formed in 1853, until when the church of St. John the Baptist had been a Chapel of Ease to Wotton. The church is outside the historic centre and conservation area, about ½ mile north in woodland, with car access from the north. Only a footpath links it to the village.
