In Mosiah 7:3, Mormon notes that this particular Ammon (Ammon1) was "a descendant of Zarahemla," or of Mulekite blood, and the reader should be careful not to confuse this person with the Ammon who was the son of Mosiah2 (Ammon2), who was of Nephite blood. One might wonder why a Mulekite would be sent to rescue Nephites that had returned into a previous Nephite territory? Perhaps there had been more interaction previously between the Mulekite people and the Nephite or Lamanite people than is mentioned in the text. And why did Mormon even mention this relationship? Perhaps if descendants of Mulek originally accompanied Zeniff, it would not be apparent to Mosiah2 whether Zeniff's group were now governed by Nephite leadership or Mulekite leadership. Nephite leadership would readily trust a Nephite king but Mulekite leadership would need some reassurance. This could have been accomplished by Ammon, who would have probably been either a great-grandson of Zarahemla or a grandson, depending on whether Zarahemla was much older than Mosiah1 or about the same age.
