There were two general factions on the ship that brought Lehi and the others to the New World—one led by his righteous son Nephi, and the other led by his wicked older brothers Laman and Lemuel, with a sub-faction who sided with Laman and Lemuel—the wicked sons and daughters of Ishmael, who had lands named after them.
19 And Ammon went to the land of Ishmael, the land being called after the sons of Ishmael, who also became Lamanites. (Alma 17)
18 And it came to pass that Ammon and Lamoni returned from the land of Middoni to the land of Ishmael, which was the land of their inheritance. (Alma 21)
13 And it came to pass that when the Lamanites saw that they could not overpower the Nephites they returned again to their own land; and many of them came over to dwell in the land of Ishmael and the land of Nephi (Alma 25)
21 And ye all are witnesses this day, that Zeniff, who was made king over this people, he being over-zealous to inherit the land of his fathers, therefore being deceived by the cunning and craftiness of king Laman, who having entered into a treaty with king Zeniff, and having yielded up into his hands the possessions of a part of the land, or even the city of Lehi-Nephi, and the city of Shilom; and the land round about—(Mosiah 7)
9 The people of the Lamanites who were in the land of Ishmael;
10 And also of the people of the Lamanites who were in the land of Middoni;
11 And also of the people of the Lamanites who were in the city of Nephi;
12 And also of the people of the Lamanites who were in the land of Shilom, and who were in the land of Shemlon, and in the city of Lemuel, and in the city of Shimnilom.
13 And these are the names of the cities of the Lamanites which were converted unto the Lord; and these are they that laid down the weapons of their rebellion, yea, all their weapons of war; and they were all Lamanites.
14 And the Amalekites were not converted, save only one; neither were any of the Amulonites; but they did harden their hearts, and also the hearts of the Lamanites in that part of the land wheresoever they dwelt, yea, and all their villages and all their cities.
15 Therefore, we have named all the cities of the Lamanites in which they did repent and come to the knowledge of the truth, and were converted. (Alma 23)
