The Stone family emigrated from England in 1848. They sailed on the Sailor Prince, and arrived in New Orleans on 20 November 1848. Jane's mother, Hannah, remarried in July 1850. Jane appears in the 1850 census living in the John Bardsley household. It appears that the family went west in 1855. Jane married Ralph B. Douglass in 1856 in Utah.
Further research is needed to determine which company they traveled with.
