As Ethel states, the only useful information you can find on the web is a copy of the title register, which will cost you �3:

However your local county record office may well have further information available. (You'll probably need to take your passport and/or driving licence, together with several proofs of address when you first visit. Record offices hold some very valuable historical documents, so they take care to check the identity of people consulting the records). Find your local register office here:
