The Stewart family is seen on the 1850 Iowa census, enumerated 12 September 1850. The family is next documented in the Utah Stake City ward by a rebaptism of both parents and son Philander on 15 April 1852. This was prior to that year's emigration season so the family must have traveled to the Valley in 1851.
Birth and death dates listed were found in a personal, online family history record (such as Family Tree, Ancestry, or My Heritage), without any accompanying documentation. Further research is needed to verify its accuracy.
