Beaver County, Nevada Genealogy
Nevada Territory with its eastern border at 116° W, and in 1862 moved Nevada's eastern border one degree of longitude east, and repeated that again in 1866, each time reducing Beaver County, Utah. Former Beaver County land in present-day Nevada was used eventually to form parts of Mineral, Esmeralda, Nye, and Lincoln, counties.
When Beaver County, Utah Territory was created 5 January 1856   from the southern part of Millard and northern part of Iron counties, Beaver County extended into present-day Nevada from Utah Territory's eastern boundary to the western edge of the Carson County between Milliard and Iron counties in Utah Territory.
