I want to know the answer to the following question:
When did Robert Louis Stevenson sail on the ship Janet Nicoll?
All the background I'm provided with is that "In 1890 Robert Louis Stevenson, his wife Fanny Vandegrift Stevenson and her son Lloyd Osbourne sailed on the Janet Nicoll, a trading steamer owned by Henderson and Macfarlane of Auckland, New Zealand, which operated between Sydney and Auckland and into the central Pacific.". Is that enough to answer the question?
