Carson County, Nevada Genealogy
Organized 17 January 1854  as part of Utah Territory. Carson County was created from the far western parts of Weber, Desert, Tooele, Juab, Millard, and Iron counties. It was enlarged in 1856, then discontinued in 1857. It was reorganized as part of Utah in 1859, but the local citizens rejected that effort and association with Utah (see Nataqua Territory). This county included all of present-day Nevada between 118° and 120° west longitude. It may also have included the Great Basin parts of eastern California.
Nevada Territory was created. It became part of Churchill, Douglas, Esmerelda, Humboldt, Lyon, Mineral, Ormsby, Pershing, Storey, and Washoe counties, and Carson City (independent city).
