http://www.Cymdeithasenwaulleoeddcymru.org.uk would be interested in any place-name collecting that anyone is collecting. Local knowledge can help in our understanding of place-names, natural history, language and dialect and can be a useful ‘bridge’ with the work of academics. This website has been collecting historical evidence on the subject for many years, mainly relating to South Wales and may be able to assist with specific enquiries.
Please take a look and see if you can help!
