Evidence from emigration and genealogical records proves that Maria traveled to Utah in 1854. She sailed to America in 1854 and was married in Utah 24 July 1855, which was prior to the arrival of that season's emigration. Further research is needed to determine the name of the company she traveled with. Her birth year is calculated from her age (31) listed on the 1860 Utah Census. Her name is listed as "Mariah Whittier."Two sisters, Emma and Frances, were also on the 1854 Windmere ship manifest with her, but they died at sea.
