The List of Historic Welsh Place Names received the Cynefin Project data from the National Library of Wales just before Christmas 2018, and since then, the Royal Commission on the Ancient and Historical Monuments of Wales has been going through them and cleansing the data in order to upload them to the List. This meant going through over 900,000 records, and pulling out each one that wasn’t actually a name, like ‘field’ or ‘house and garden’. This work is now completed, and the Commission is happy to announce they have an additional 515,902 names to add to the list.
