Mary Leicht

She is Mary "Cornwall" on the Warren Company roster.  Her mother had died in England and her father (George leicht) married Mary Ann Hunt Miles but he too died in England.  Eleven-year-old Mary Leicht sailed for America on the ship General McClellan with her widowed step-mother Mary Ann Hunt Miles Leicht who married John Cornwall aboard during the voyage (see letter of Thomas Evans Jeremy, 19 June 1864 on the Mormon Migration website.)  Thus Mary Leicht crossed the plains as Mary Cornwall.
