Even so, if you've a few hours spare, I'm sure some extra help wouldn't go amiss. You can find out more here.
The indexing of Lord Viscount Morpeth's Testimonial Roll is one of Ancestry's World Archives Project, meaning that volunteers transcribe and index the document and it is then made available to researchers across the world free of charge.
