Deletion of Thomas Otho Travers

Comment: The question here in my mind is whether Travers qualifies under  or (8), or alternatively if this should be renamed to cover the book. He is covered a bit, e.g. https://books.google.co.il/books?id=_A8TAQAAMAAJ&q=%22Thomas+Otho+Travers%22&dq=%22Thomas+Otho+Travers%22&hl=en&sa=X&ved=0ahUKEwjz9PTb4LnZAhWQyaQKHRusBSk4KBDoAQg7MAU, however his main claim for fame is authoring the "The Journal of Thomas Otho Travers (1813-1820)" which is an important source for covering Stamford Raffles (including the founding of Singapore) and is widely quoted with some coverage of Travers resulting from the quotation
