In 1 Nephi 16:34 we read of Ishmael’s burial:
And it came to pass that Ishmael died, and was buried in the place which was called Nahom.
In addition to there being a place called Nahom in exactly the correct place, there is also evidence of an Ishmael being buried there around the 6th century BC. Sabina Antonini and Alessio Agostini even argue that Ishmael was part of a group who “were caravaneers engaged in commerce throughout the western side of the Peninsula”.
Why think this is simply a coincidence?
