Wyoming County Genealogy
An important research consideration for Wyoming is that its counties, as they exist today, went through many changes in a relatively short period of time. When organized, it included four counties from Dakota Territory—Albany, Carbon, Carter, and Laramie—and Green County from Utah Territory. When the territory was organized on 19 May 1869, Uinta County was created from the formally unorganized portions of Utah and Idaho. At that time, Carter County was renamed Sweetwater. By 1923, Wyoming had been subdivided into its present twentythree counties.
In addition to the territorial and homestead land records held by the Wyoming State Archives, the county clerk holds land records filed by county after the date of formation. District clerks are to be addressed for court and probate records, though most will also be found at the Wyoming State Archives. No county birth or death records exist before mandatory statewide recording, but most counties hold marriage records. Some even date before incorporation. Contact the archives prior to conducting extensive research on the county level to determine which county records have been deposited at the Wyoming State Archives and which are only available on a county level.

Wyoming State History
Wyoming (state), in the western United States. It is bordered by Montana on the north, South Dakota and Nebraska on the east, Colorado and Utah on the south, and Utah, Idaho, and Montana on the west. The land within these borders was first called Wyoming in 1865, when a member of the Congress of the United States from Ohio suggested that a new territory be carved from Dakota, Utah, and Idaho territories.
The name Wyoming is a contraction of the Native American word mecheweamiing (“at the big plains”), and was first used by the Delaware people as a name for the Wyoming Valley in northeastern Pennsylvania. Wyoming is known as the Cowboy State and the Equality State. The latter recognizes Wyoming as the first state to specifically give women the right to vote, which it did as a territory in 1869 and retained upon entering the Union. Cheyenne is Wyoming’s capital and largest city.
Wyoming became a territory in 1868 and entered the Union on July 10, 1890, as the 44th state. It has a wealth of mineral and agricultural resources, and mining and agriculture still play major roles in the state’s economy. The state is thinly populated and ranks 50th among the 50 states in population. Wyoming is a place of great natural beauty, and each year large numbers of tourists are attracted by the state’s unspoiled scenic wonders.
