The Lemuelites were descendants of Lemuel, the second son of Lehi and Sariah, counted among the Lamanites. In an early list of Lehi’s posterity they appear alongside the Nephites, Jacobites, Josephites, Zoramites, Lamanites, and Ishmaelites; Jacob then states that he will no longer distinguish the groups by these names, but will call all who sought to destroy the people of Nephi “Lamanites” (Jacob 1:13–14). Later passages still itemize the composite, naming the Lamanites as composed of the Lamanites, the Lemuelites, and the Ishmaelites, together with the Nephite dissenters (Alma 47:35; Alma 43:13).
Among the Lamanites converted by the Nephite missionaries, those who joined the people of the Lord included no Amalekites, Amulonites, or members of the order of Nehor, but “actual descendants of Laman and Lemuel” (Alma 24:29).
After Christ’s ministry in the land and the peace that followed, the names returned as groups rejected the gospel: those who rejected it “were called Lamanites, and Lemuelites, and Ishmaelites,” and they did not dwindle in unbelief but rebelled against the gospel of Christ and taught their children to disbelieve (4 Nephi 1:38). At the close of the record the Lemuelites are again named with the Lamanites and Ishmaelites among the forces fighting the Nephites, the two parties then both called Nephites and Lamanites (Mormon 1:8-9).
