Mary Baker's Necklace

Origins
Mary Baker (nee Willcocks) (1791 – 24 December 1864) was a noted impostor who went by the name Princess Caraboo. She pretended to be from a far away island and fooled a British town for some months.

Mary claimed to be a princess from an island in the Indian Ocean, Javasu, who had been captured by pirates until she jumped ocerboard in the Bristol Channel and swam ashore in Almondsbury in Gloucestershire, England.
