Joseph initially traveled to the Salt Lake Valley as a part of Thomas Johnson's Fifty in the Benjamin Hawkins Company in 1850.
From family histories of Joseph Knight, Jr. on FamilySearch, family tradition says that Joseph Knight was asked to marry Adeline Johnson and Abbie Weldon as plural wives to provide temporal support for these "single" women. We do not find a death date for Adeline's first husband, Isaac Butterfield, so she was probably a young widow. It is likely that Joseph Knight brought Adeline to Utah with him in the 1850 Benjamin Hawkins pioneer company.
