With her husband Richard and two children (Richard, age 12, and Ann, age 10) she crossed the Atlantic in 1855 on the ship Juventa arriving in Philadelphia on 5 May. According to the published roster of the Milo Andrus Company she crossed the plains with her husband and one child. (The Andrus roster was complied before the company's departure from Mormon Grove, Kansas on 4 August.) Since the son Richard was baptized at Goshen, Utah in 1857, he must have been the child that crossed the plains. Daughter Ann must have died sometime between the family's arrival at Philadelphia and their departure from Mormon Grove. Another daughter (Hannah) crossed the ocean on the ship International in 1853. Family tradition says she died of Cholera on the Missouri River. Sarah's death date is from Utah State History Cemeteries and Burials Database. At the time of the 1856 Utah Territorial census Sarah and her family were living in Pleasant Grove, Utah.
This Sarah Mason Johnson's parents are Anthony Mason and Hester Vaughn and should not be confused with the Sarah Mason Johnson who died in 1881.
