In 1850 Rebecca was living in the Iowa household of her son Henry. In the 1856 Utah Territorial census they were living together in North Kanyon Ward, Bountiful, Utah. Her travel to Utah is mentioned in her son's obituary.
Our Pioneer Heritage, a secondary source, states that she came with "Captain Clark's company." We are not aware of an individual by that name who served as a Captain of 10, 50, or 100 in 1852.
