Another contributor to M2C has been History of the Church.
Here's one example:
25 June 1842 - The Prophet Joseph "sat for a drawing of my profile to be placed on a lithograph of the map of the city of Nauvoo." He also mentions the work of "Messrs. Stephens and Catherwood" who have "succeeded in collecting in the interior of America a large amount of relics of the Nephites, or the ancient inhabitants of America treated of in the Book of Mormon" (History of the Church, 5:44).

When your theory relies on a premise you know is false, I think it's time to revisit the theory.
