The [[Tithe Commutation Act of 1836]] and an amending act in 1837 established a process by which tithes could be converted to money payments. This required the drawing of an accurate map (the accuracy of which was certified by commissioners) showing all the land in the parish. The map was accompanied by a schedule showing the owner, occupier and a description of the land in the parish including individual fields - sometimes with field names. (The description may be short - house and barn, arable, etc.)<ref>Harley p.35</ref> Three copies of these maps and schedules were prepared, one of which was held centrally by the Tithe Commissioners, one locally in the parish church and one in the diocesan registry<ref>Munby</ref>.
