Llyfrgell Genedlaethol Cymru/National Library of Wales
The National Library of Wales (LLGC/NLW) is the premier centre for family history research in Wales, holding as it does abundant records covering the whole of Wales.
Apart from its collections of printed materials, which include electoral lists, newspapers, journals, and directories, NLW holds a whole range of such useful resources for genealogical research as parish and non-conformist registers, marriage bonds and affidavits, probate documents, estate records and personal papers, pedigree books, copies of census returns, plans, sale catalogues, and tithe maps and schedules.
For further information on these and other records useful for family historians, please consult the National Library of Wales website.
You can access several LLGC/NLW catalogues on the NLW catalogue and electronic resources page of the website.
