Traveling with his mother Rebecca Fausett Saunsocie and his step-father Louis Saunsocie. Son of Cornelius P. Lott. Isaiah's name also appears on the Journal History record for the 1851 John G. Smith company. It is uncertain why his name would appear here. He would have been only four at the time and his parents were not with him. His obituary also states that he came in 1851. However, it is still most likely that he traveled with his parents in 1852.
His birth date is confirmed by Utah Stake City Ward records at the time of his baptism on 26 November 1854.
