Nephi

The following are all from the Book of Mormon, except for the Hebrew spelling of Nephi.

Nephi (Hebrew נפי Nəphî) was a great prophet and was the son of Lehi. He lived around 600 B.C. He was the anscestor of the race of people known as the Nephites, who lived in the Americas from around 590 B.C. to 400 A.D., when they were destroyed by the Lamanites because of their wickidness.

After the death of the beforementioned Nephi, kings that followed were named after him, being called Second Nephi, Third Nephi, and so on.

Another Nephi lived around the time of Christ, and he was a descendant of Lehi aswell. This Nephi was the son of Helaman. Nephi also had a son who was called Nephi after him.

There was also a region called the Land of Nephi, and a City of Nephi.
