For a thousand years the extent of the arable land in Brampton has remained as it was defined in the Doomsday Book. That Norman record reduced the economic activity of the feudal settlement to a single paragraph. The plough lands were said to extend to a Caracute and a Virgate. (A Caracute being an area equivalent to that which could be ploughed by eight oxen in one season and a Virgate being the amount ploughable by two oxen in a season). Thus totalling around 150 acres of better drained land
The actual extent of the plough lands can be roughly estimated today from a large scale OS map as long as you adopt some basic rules. For example, start near the Church as the assumed centre of the village; assume that the modern roads follow ancient routes; ignore the Victorian railway line and trust the line shown as the Parish boundary. If we use the known field names encompassing Hall and Street Farms the area coincides with those known as Church Field, Seven Acres, Kiln Field, Hill Field, Winter Letts, Topletts and the Town Field. It is a very neat fit and 150 acres looms out of the plan.
