Laura Kesler
Although a non-contemporary typescript list in Journal History (Supp. after 31 Dec. 1851, 6A) lists the Kesler family as coming in the 1851 John Brown company, Kesler's autobiography states that he was a captain of the 2nd Ten in Orson Pratt's company. Pratt was a nominal leader in the Cummings company so the Kesler family must have traveled in the Cummings company, not the Brown company.
Her death certificate lists her birth date as 4 April 1850, and shows her name as "Laura Murray."
