Anyone with an interest in local history is well-served in Wales as old newspapers, wills, bardic genealogies etc are available on-line and free of charge. Only photocopied parish registers and civil registration records have been handed over to the fee-devouring private sector. The latest treat we are promised are on-line tithe maps together with the schedules detailing field names etc. The map for Llanelwedd has already been uploaded, see here, accompanied by a short article, here.
The tithe maps and schedules date back to the 1840s, a time when language shift in most of Radnorshire was either in progress or had only recently been completed. The extent and nature of Welsh language field names should provide clues to the situation in the county's varied parishes, as well as information on dialect, social history and nature.
