Only the last document is downloadable from the National Archives for a small fee. For the remainder it means a personal visit to the archives to order and view the documents in person, or find someone to do the research on your behalf. If you're lucky someone might do it as a favour, otherwise it means paying a professional researcher. You might find a personal visit so much more rewarding...
