Wyoming became the 45th state admitted to the United States on 10 July 1890. Up until 1848, at the end of the Mexican-American War, southwestern Wyoming was part of the Mexican Territory. Different parts of Wyoming were claimed by Spain, France and England, to see how it all came together read this in the FamilySearch Research Wiki. There are 11 Indian Tribes here, information on various record sources, collections and how to research members of these tribes is located here.
When doing research here, one needs to know who owned what to locate ancestral records. While the U.S. Census started in 1790, the first census to cover this area was the 1850 and it was enumerated as part of the Utah Territory in the ‘Green River Precinct’ at the end of Weber County. As the area known as Fort Laramie today was unorganized territory it was not enumerated. To fully understand what was enumerated for each census, review this FS wiki page.
Statewide registration of births and deaths began in July, 1909, while marriage records didn’t begin till May, 1941. Only a few counties kept records of births and deaths a few years before 1909, while many counties began recording marriages soon after the county was organized. Some county marriage records go back to the 1860s with more than 23,800 marriages indexed on the Western States Marriage Index website.
FamilySearch has four sets of online records here. The State Archives has a Death Certificate database covering 1909 to 1967. Ancestry.com has 27 databases with the Wills and Probate Records covering 1864-1915. For a look at what’s available online check here.
Major repositories for records not online are listed here, also the Family History Library’s collection is available through Family History Centers.
