This website has sections on Bristol, Cornwall, Derbyshire, County Durham, Exmoor, Herefordshire, Kent, Oxfordshire, Sussex and Wiltshire. It is run by the Victoria County History people and the aim is to work with local communities to produce books and web pages about their areas. Lots of goodies here if your ancestors came from one of the places covered.
