Alma 43:16

"The famous last warrior in the Book of Mormon is Moroni, who fights with tens of thousands of others at the Hill Cumorah. Interestingly, there are islands off the east coast of Africa named the Comoro Islands (also spelled Comora), and the capital is Moroni. A common school book in Smith's day was Geography Made Easy, by Jedidiah Morse, 1813. On page 356 he mentions the 'Comora Islands' off the coast of Africa. Smith could have also heard of these islands in connection with his treasure-digging, as the famous pirate Captain Kidd, along with many other pirates, stopped there. It was rumored that he later buried his treasure somewhere in New England." -Jerald and Sandra Tanner, Joseph Smith's Plagiarism of the Bible in the Book of Mormon, p. 26.

Ronald V. Huggins states, "One day in late March 1697, a ship... arrived at the Island of Mohilla, one of the Comoro Islands... It would not depart again until April 18. Its captain, William (a.k.a. Robert) Kidd, did not know he would soon become one of history's most famous, and notorious, pirates. In those days pirates, even famous ones, were no oddity in the Comoros.. But it was the rumor of an enormous treasure trove buried somewhere, or scuttled along with the mysteriously missing Qedah, which did most to immortalize the man. The fact that Kidd was arrested so soon after arriving in Boston made it highly likely, or so many believed, that his treasure was still out there, somewhere, waiting to be discovered. Thus, Kidd's treasure became the most vigorously sought pirate's prize of all. For Mormons, the fact that the pirate was hanged for crimes allegedly committed in the vicinity of Moroni on Grand Comoro is significant because the hunt for his treasure came to play a part in the story of Moroni on Comorah." -Ronald V. Huggins, From Captain Kidd's Treasure Ghost to the Angel Moroni, Dialogue: A Journal of Mormon Thought, vol. 36, no. 4 (Winter 2003): pp. 17-19.
