Onesacre is mentioned in the Domesday Book as 'Anesacre' which derives from a Scandinavian personal name. It was one of many small settlements with single fields established by the Anglo-Scandinavian period (Hey 1986, 22; Hey 1979, 24). It is associated with the adjacent fields to the northeast. Onesacre currently consists of three farms. Amongst the farm buildings remain several dating to the 17th century as well as some dating to the 18th and 19th centuries. Legibility of the previous post-medieval vernacular building tradition is significant.
