Diantha's husband (John Social Rolph) and children (George, Alta, John, and Albert) traveled to Utah in the 1860 Warren Walling Company. However, Diantha was not listed in Walling company sources. She was located with her family in the 1870 Census in Rockville, Kane County, Utah. Also, family tradition from Family Tree at FamilySearch.org states that she mothered three more children in Utah between 1861 and 1865, which suggests that she traveled to Utah before 1868.
At this time, Birth and death dates listed reflect family tradition from Family Tree. More research is needed to confirm them.
