Evidence from genealogical records prove that the Coppin family came to Utah between 1850 and 1852. A child was born in Missouri in January 1850. The first evidence to place them in Utah is the birth of another child 27 November 1852. James Robert appears in the Salt Lake City 11th Ward records in 1852, and he purchased land in Salt Lake in January 1853, which was prior to the arrival of that season's emigration. In both the land and church records his name is shown simply as "Robert Coppin." Further research is needed to determine the year they came to Utah and the name of the company they traveled with.
They traveled on to California in 1853 or 1854, where another child was born 8 August 1854.
