Wyoming Counties records differ vastly from county to county in either quality not to mention quantity. Some are already carefully preserved while some have been substantially abused and neglected.

Wyoming Counties – There are 23 counties that exist in Wyomin. Each one holds records that may include: Land, Estates, Taxes, Vital Records, Divorces, Naturalizations, Voter Registration, Court Records. Other records may also be included. However, other resources do need to be consulted.

There were originally five counties in the Wyoming Territory: Laramie and Carter, established in 1867; Carbon and Albany established in 1868; and Uinta, an annexed portion of Utah and Idaho, extending from Montana (including Yellowstone Park) to the Wyoming-Utah boundary. On July 10, 1890, Wyoming was admitted to the Union with thirteen counties.

Today’s Wyoming counties did not always exist in the present form. They went through many different changes in the space of a few short years. In the beginning Wyoming Territory had 5 counties. They were Carbon, Carter, Laramie and Albany, which were originally part of Dakota Territory, and Green County, which was originally part of Utah.

On May 19, 1869, the newly-organized territory added Uinita County from portions of Idaho and Utah that were previously unorganized. At that same time, Carter County became Sweetwater County. Wyoming now has 23 counties, which were all in existence by 1923.

The Wyoming State Archives holds several homestead land records and territorial records for the state of Wyoming. However, county clerk offices also hold several important records, especially land records beginning at the date that the county was formed. Probate and court records, meanwhile, can be found in the offices of the district court clerks. Although, many are also on file with the Wyoming State Archives. Although many counties have early marriage records on file, there are no death or birth records available at the county level. Some marriage records even exist from the time before Wyoming was incorporated. It’s always best to consult the Wyoming State Archives first. They can provide information on which records they hold and which records must be researched in specific county offices. See also a list of links to county and county seat government run websites.

Wyoming burned county courthouseThe damage to Wyoming courthouses tremendously has a affect on genealogists in almost every way. Not only are most of these historic structures torn from all of our lifetimes, so are the documents they kept: marriage, wills, probate, land records, as well as others. Once destroyed they are gone forever. Even though they have already been put on mircofilm, computers and film burn too. The most sad aspect of this is the reason that virtually all of our courthouses are destroyed at the hands of arsonist. Though, not all records were destroyed. A number of Wyoming counties have dealt with a loss of records due to courthouse fires, floods, and theft.
