United States Wyoming History
Wyoming is a Delaware Indian word meaning "mountains and valley alternating". The vast state of Wyoming was first inhabited by the Arapaho, Bannock, Cheyenne, Comanche, Crows, Cree, Dakota, Gros Venutreno or Chumashan, Gosiute, Kiowa, Kiowa-Apache, Menominee, Numa, Paiute, Pawnee, Shoshoni, Sioux, Ute (Southern) Indians.  For more information see the Indians of Wyoming page.
Portions of what is present day Wyoming were at one time claimed by Spain, France, and England. The acquisition of the territory by the United States was completed through five major annexations—the Louisiana Purchase in 1803, the Treaty of 1819 with Spain, cession by the Republic of Texas in 1836 and partition from Texas after it was annexed in 1845, the Treaty of Guadalupe Hidalgo in 1848 after the Mexican War, and the international agreement with Great Britain in 1846 concerning the Columbia River country.
In the early 1800's explorers, pioneers,fur traders (mountain men), fort builders like Jim Bridger and emigrant trails began to cross the land. John Jacob Astor worked to establish a cross continental route for fur trade. This would be followed by missionaries, fortune seekers, soldiers, Pony Express riders, telegraph operators, and cattle drivers. Big game hunts lured in the English and French nobility. Railroad builders, coal miners, cattle barons, cowboys, sheep owners and herders, outlaws and rustlers, diamond swindlers, brave homesteaders, and settlers all had either success or tragic results in their quest to make a new life out of this land rich in resources and expanse.

Some of the most valuable sources for family history research are local histories. Published histories of towns, counties, and states usually contain accounts of families. They describe the settlement of the area and the founding of churches, schools, and businesses. You can also find lists of pioneers, soldiers, and civil officials. Even if your ancestor is not listed, information on other relatives may be included that will provide important clues for locating your ancestor. A local history may also suggest other records to search. Local histories are extensively collected by the Family History Library, public and university libraries, and state and local historical societies. The United States Research "History" page cites nationwide bibliographies of local histories which include histories of Wyoming.

State Histories Useful to Genealogists
Good genealogists strive to understand the life and times of their ancestors. In this sense, any history is useful. But certain kinds of state, county, and local histories, especially older histories published between 1845 and 1945, often include biographical sketches of prominent individuals. The sketches usually tend toward the laudatory, but may include some genealogical details. If these histories are indexed or alphabetical, check for an ancestor's name.
