Harriet came from England with her father George, mother Eliza and family in 1864 on the ship General McClellan.
James and Harriet Dutton are also on the roster of the 1864 Joseph Rawlins company that was printed in the Deseret News. Since we have their names on a handwritten and a newspaper roster for being in the Warren company, there is greater proof that they traveled in the Warren company than in the Rawlins company. Also traveling in this company was Harriet's parents and siblings.
Her birth and death dates are confirmed by the burial record.
