In the Doomsday Survey, 'Epton' (then known as Shipton[thorpe]) was held by Earl Morcar, followed by the king (VCH II, 196, 319).
A medieval dedication is not known and the Doomsday Survey does not mention any church there. Shipton was a peculiar in the parish of (Market) Weighton, where the dedication was and is to All Saints.
Shipton and Thorpe were treated as separate settlements until quite recently. For example, the church was described as at 'Shipton' in Fallow 1909; it is also listed as 'Shipton' in Henry and Zarnecki 1957. Place-names with 'Thorpe' are about a mile NW of Shipton. The names were joined at the request of the Post Office, as there were so many 'Shiptons'.
