Margaret Phillips
Her obituary of her daughter Eliza Morris states that she came to Utah with her mother in 1852, but by 1851 she was married to William Price Thomas (marriage location unknown), and she gave birth to a baby in Brigham City, Utah on 29 Mary 1851. Margaret's obituary appears in the "Memories" section of her FamilySearch account, and it also states that she came to Utah in 1852. Further research is needed to determine the year of their arrival and the name of the pioneer company with which they traveled to Utah.
