Manors, townships and constableries

In some parts of the country manorial boundaries generally correspond with ancient parish boundaries, and the boundaries of ancient parishes are usually the same as those of modern civil parishes. In north-east Derbyshire, however, the position is more complicated, since several of the large ancient parishes were divided into smaller townships in the 16th century for local government purposes and it is these, rather than the ecclesiastical parishes, that become civil parishes in 1894. A further complication in this area is a `constablery', i.e. the area over which a petty constable had jurisdiction, is not always the same as either a township or an ancient parish.
