• William Walker Rust participated in the Mormon Battalion. As a member of the Sick Detachments, he reached Utah in 1847 but soon returned to Winter Quarters. He then traveled with his family in 1850 with both the Snow and Roundy companies. As companies traveled so closely, it was not uncommon for families to move from one to another. Later, he again made a trip east and returned with the Charles Harper Company of 1855, in which he served as the Captain of the English Ten.

  His birth date is confirmed by Seventeenth Ward records at the time of a rebaptism on 14 March 1857.
