William Dearborn Brown, his wife, and family joined up with the Walling Company. However, they were not listed in the (Emigration List for Spring, 1860) company roster. William Dearborn's account of the journey mentions his wife and family. Also, The obituaries of Amasa David Brown, state that Amasa, William Dearborn Brown, and Harriet Francis Hatch Brown came to Utah together in 1860.
More research is needed to confirm Amasa's date of birth as the 1900 Census states he was born in 1857.
