The only likelihood of success with the Land Registry will be if the name sought is that of the first lessee on a long lease of the flat. The date is around the time that the various parts of the old County of London became compulsory registration areas, so it is possible that one or more titles were registered. What is more, it is now possible to get a copy of the register as it was on a specified date in the past for £8, twice the fee for a current copy. The catch is that this facility is available only for dates since the title was entered on the computer. It is just possible that a lease granted around 1903 will still be mentioned on the register, but that is about the only chance of success. If the person sought were a weekly (or other short-term) tenant, there is no hope with the Land Registry. Jeremy Wilkes
