The Hansen family crossed the ocean by way of the ship Westmoreland in 1857. They began their journey to Utah with the 1857 Christian Christiansen handcart company, as indicated by Martin Hansen's autobiography, but stopped in Genoa and stayed there until 1861.
Evidence from genealogical and newspaper records confirms that the Hansen traveled to Utah in 1861. A child was born in November 1860 in Iowa, but the first documentation to place them in Utah is the birth of another child in February 1862, which was prior to the arrival of that season's emigration. The obituary of Caroline also states that the family came to Utah in 1861. Further research is needed to determine the name of the company with which they traveled.
