The Domesday Book records two manors, the larger held by Hugh of Walter, brother of Saher, and this later became the manor of Wrest. A smaller manor, believed to be that of Newbury, was owned by a concubine of Nigel d'Aubigny. The first market was held here weekly on Tuesdays and annual fair on 1 May from 1318.
