A Celebration of the Family: English Genealogical Resources for the Family Historian A very good site for the English genealogist. Its all packed into the one page though which is one of the drawbacks to an otherwise decent service.
The UK & Ireland Genealogical Information Service(GENUKI) One of the best sites you are likely to come across in the UK for a genealogy site. It has broken the site into the relevant topics and its very easy to find your way around.
Public Record Office - The National Archives The UK's national archive site. Nicely designed with lots of interesting articles to read about. It has the necessary section for the family researcher.
