William emigrated with his parents Joseph and Emma from New Jersey. Their youngest son, Joseph Fillmore Chamberlain, was born in New Jersey on 19 September 1852 and died in Salt Lake on 9 October 1853, so the family must have traveled in 1853, but further research is needed to determine the name of the company they traveled with. Death date taken from death certificate. Birth date take from 15th Ward records made in 1857.
