• Based on information in Aurelia Spencer Rogers's autobiography (Life Sketches, 1898 ed., 47-50), we conclude that the Bullock family traveled to Utah in the 1848 Brigham Young company. Kenneth C. Bullock, a Bullock family historian, arrived at the same conclusion (A Genealogy of James Bullock and Mary Hill, Latter Day Saint Pioneers, 1964, 4, 9).

  Her death certificate shows her name as "Elizabeth Bullock McArthur."  Her entry on the Find a Grave website includes her obituary, which confirms her travel to Utah in 1868.
