While the settlers at Franklin were effectively governed by Utah Territory until 1872, the settlers were actually located within Washington Territory from 1860 to 1863 and not within the boundary of any county until Shoshone was created in 1861. They became part of Idaho County in 1861, and Boise in 1863. And finally, under Idaho Territory, they briefly became part of Owyhee County before being transferred to Oneida County in 1864. At the 1870 census, the three Franklin County precincts were enumerated in Cache County, Utah, containing 1,053 residents. In 1885, the northern portion of the county was transferred to Bingham County at its creation. At the 1890 Census, Bingham and Oneida Counties returned five precincts of Dayton, Franklin, Oxford, Preston, and Treasureton with 4,969 residents. The Oxford and Treasureton precincts were transferred to Bannock County at its establishment in 1893. Bannock County retained the Oxford precinct and renamed the Treasureton Precinct as Cleveland. By 1900, Oneida contained seven precincts that would later be entirely within Franklin County. Together, the nine precincts comprised a population of 6,566 at that time. The Cleveland and Treasureton areas were transferred to Franklin County in 1918. The portion of the Thatcher area in Franklin County remained within Bannock County until 1946.
