Amos, son of Nephi, is a Nephite record keeper mentioned in the Book of Mormon. He had custody of the Nephite Record for 84 years, approximately from A.D. 110 to 194, and two verses, 4 Nephi 1:19-20, are purportedly an abridgment of his writings. Outside of the Book of Mormon account, there is no evidence that Amos existed. In the Book of Mormon, the Nephites (BoM Arabic نافيين Nāfiyyīn) are a people descended from or associated with Nephi, a prophet who traveled with his family from Jerusalem to the Western Hemisphere circa 600 B.C. at the urging of God. ...

Nephi's father, Lehi, was also a prophet who, prophesied of the destruction of Jerusalem, left Jerusalem with a few others around 600 BC and were eventually directed to the New World.
Both Nephi (1 Nephi 19:3) and Mormon (Words of Mormon 1:7) recorded that the small plates were made for a "wise purpose" that was known to the Lord.
The large plates of Nephi were continually maintained until about AD 385, when the prophet Mormon, seeing that the destruction of the Nephite nation was imminent, abridged the large plates of Nephi.
