Joseph and his wife Ingray arrived in Utah between 1857 and 1859. They do not appear on the 1856 Utah census. The first documentation to place them in Utah is the 1860 Utah Census, which was taken 14 July 1860, prior to the arrival of that season's emigration. Their baptism, membership and association with the Morrisite church occurred in 1861.
The 1860 Utah Census in Cache Valley shows "Joseph Warner," age 44, born in Hanover, Germany, and Ingray Warner, age 43, born in Sweden. The Morrisite Roll of Membership lists their names as "Joseph Warner" and "Ingray Werner." The Morrisite War record lists his name as "Joseph Werner."
