From MormonWiki
Jacobites is a term used over the course of the entire
Book of Mormon to refer to a subgroup of the
Nephites. The name originates from Jacob, the son of
Lehi and brother
Nephi The name continues over the generations. While it can be inferred that this refers to Jacob's direct descendants, it is interesting to note that the name persists in the records as a clear subgroup of the Nephites up until the destruction of the Nephites.
