Moroni's obituaries indicates that he came to Utah during 1851. He was first baptized by James G. Browning in Ogden in the autumn of 1851.
He possibly traveled with his step-mother, Esther Jones Brown, in the Spencer/Eldredge Company (1847). Or, he could have traveled with his other step-mother, Sarah Steadwell Brown, in the Kimball Company (1848). However, he does not show up on the records for either company. Nor does he show up on the 1850 census with the rest of the family.
