I am sure most already know this but the apocrypha in the Bible used by Smith had the name Nephi in it.
Etymology of Nephi
Based on a non-Latter Day Saint or secular perspective, hypotheses for the name's origin include: its appearance as a geographic name in 2 Maccabees of the Apocrypha ("And Neemias called this thing Naphthar, which is as much as to say, a cleansing: but many men call it Nephi.")
