According to Brant Gardner, if the land of Zarahemla was named after Zarahemla (or his father), then his group would not have been in that spot for very long, although they might have lived in the general locale for some time. Although Omni 1:16 states that they were brought by the hand of the Lord "into the land where Mosiah discovered them; and they had dwelt there from that time forth," the "land" referred to might be referring to a larger territory and not the specific local land where Mosiah found them.
