Rio Virgin County, Utah Genealogy

United States Utah  Rio Virgin County

Rio Virgin County, Utah Territory (or Rio Virgen) was created by the Utah legislature on 18 February 1869 from part of Washington County. This was in response to the US federal government on 18 January 1867, moving the western boundary of Utah territory east, giving that land to Nevada. But when all legal recourse had been exhasted, Utah accepted the change and discontinued Rio Virgin County on 16 February 1872.

Rio Virgin County was created to serve the residents of Mesquite and Bunkerville which the legislature wanted to keep in Utah, resisting the transfer to Nevada. The US federal government conducted a survey, which showed the land in Rio Virgin County was mostly in present-day Nevada and a little in Arizona Territory. . When the county was dissolved, the tiny sliver actually in Utah was restored to Washington County.
