Beryl Evans presents a detailed, accessible, authoritative guide for anyone who is eager to research ancestors from Wales. She describes the key archival sources and shows how the development of new technology, the internet in particular, has made them so much easier to explore. Drawing on her long experience of family history work, she gives clear practical advice on how to start a research project, and she sketches in the outlines of Welsh history, Welsh surnames and place-names and the Welsh language.
