Mary sailed to America in 1849 on the ship Ashland with her husband Stephen and children. Her husband Stephen died in 1849 on the Mississippi River.
Her surname is "Wood" on the ship Ashland.
Arrived in Utah sometime before she gave birth to a son on 27 September 1851 at Salt Lake City. Her husband's parents crossed the plains in the Gully/Spencer company in 1849, so it is possible they were in that company as well, but further research is needed to confirm that.
