The maps below are widely available on the internet. There are many other excellent and informative mapping services which cannot be reproduced here for copyright reasons but which are well worth consulting. In particular, the National Library of Scotland website has an extensive collection of OS maps, notably the highly detailed OS 25 inch series produced between 1841 and 1952. This site also offers amazing zoom and overlay facilities.
In 1770 the Harvey family owned most of the lands in and around Hempstead. A survey was conducted by Owen Swan which mapped all the separate farms and holdings and gave details of the measurement of each field in acres, rods and perches. The complete survey can be found here.
Since Anglo-Saxon times, tithes had been levied on people which entitled the church to one tenth of their annual revenue or produce. By the early 19th century the tithe system had become unwieldy and unpopular. The Tithe Commutation Act 1836 converted tithes into cash payments (which were eventually abolished in 1936). Tithe awards were based on detailed. large scale maps of each parish, giving the name of the holding, the landowner and occupier, the type of cultivation (pasture, arable, woodland etc) and the measurement in acres, rods and perches. These links will open the 1842 Tithe Award map and the key to the various entries.
