The Davidson family came to Utah between 1856 and 1859. Hans and his wife had a child born Oct. 1855 in Denmark. The first documentation to place them in Utah is a child born Aug. 1859. In the 1900 U. S. census a son, Hans Thomas (but listed as T. Hans Davidson), reported that he immigrated in 1857. A secondary source says the family traveled to Utah in the Iver N. Iverson company of 1858. Further research is needed to narrow the year of travel and to verify the name of the company with which they traveled.
