I doubt the title is appended because of any need for disambiguation I note that the vast majority of the entries in Category Barons in the Peerage of the United Kingdom have the title appended to the name the main exception being former Archbishops of Canterbury but there are also a few others who seem to be covered by Wikipedia Naming conventions royalty and nobility British nobility according to which There are several exceptions to these rules Peers who are almost exclusively known by their personal names e g Bertrand Russell not Bertrand Russell 3rd Earl Russell Peers who are very well known by their personal names and who only received a title after they retired e g Anthony Eden not Anthony Eden 1st Earl of Avon Margaret Thatcher not Margaret Thatcher Baroness Thatcher An exception to the above exceptions is where the peerage title is useful for disambiguation e g Chris Smith Baron Smith of Finsbury When one holder of a title is overwhelmingly the best known e g Alfred Lord Tennyson and Lord Byron So it looks to me as if the name should stay as it is You could also ask at Wikipedia WikiProject Peerage and Baronetage
