Idbury is listed in the Domesday Survey as a settlement worth £12, and held of the king by Ralph de Mortimer and re-gifted to Oidelard. No church is mentioned in the Survey but a chapel must have existed by the 12thc. In the late 11thc Idbury was presumably dependent on the church at Swinbrook, perhaps functioning as a chapel of Shipton under Wychwood and Brixworth - all at the time attached to the Salisbury cathedral.
