I want to know the answer to the following question:
In what publication did the name Rajasthan first appear?
All the background I'm provided with is that "John Keay, in his book India: A History, stated that "Rajputana" was coined by the British in 1829, John Briggs, translating Ferishta's history of early Islamic India, used the phrase "Rajpoot (Rajput) princes" rather than "Indian princes".". Is that enough to answer the question?
