Tithe maps are no exception. A number of Welsh tithe maps were compiled from old surveys. The researcher should seek to ascertain, therefore, how the maps were made. While the maps can often carry a wide range of information, certain aspects, such as rights of way, were of no concern to the Commissioners, and consequently such information on tithe documents is often ambiguous and imprecise. This computerised database has been used to produce the listing of Welsh tithe maps in An atlas of Welsh tithe maps, in the press.
Most tithe districts are parishes, but a minority are hamlets or townships.
It is by this name that the entry will be found in the printed listing. All these variants have been incorporated in the index to the printed listing. Territorial units have changed many times since the creation of the tithe districts. Later ecclesiastical and civil parishes, together with modern communities have also been cross-referenced and included in the published place name index. Nature of the Printed Listing The listing records all tithe districts and tithe files relating to Wales.
