Taos County, Colorado Genealogy
The southern part of present-day Colorado east of the Continental Divide, that is parts of Archuleta, Conejos, Rio Grande, Mineral, Hinsdale, San Juan, Saguache, Alamosa, Costilla, Las Animas, Huerfano, Custer, Pueblo, Otero, Bent, and extreme western edge of Baca counties were part of Taos County, New Mexico Territory from its creation in New Mexico Territory in 1852 until 1860 when the eastern half of Taos County was split off as Mora County. 
- 1852 Taos County, New Mexico Territory created as an original county from an old Mexican partido. In theory it extended west to the California border including parts of Arizona and later Nevada
- 1854 Rio Arriba County absorbed the western part of Taos County in New Mexico Territory.
- 29 December 1863 Arizona's three judicial districts were established by Arizona Territory Organic Act from part of New Mexico Territory
- By November 1864 Mohave County was created by the Arizona legislature as an original county from parts of the 2nd and 3rd Judicial Districts. A part of the 2nd Judicial District eventually became part of Nevada
- 22 December 1865 Pah-Ute County was created by Arizona from part of Mohave County
- 18 January 1867 Pah-Ute County, and Mohave County, Arizona Territory west of the Colorado River and west of 114° west longitude were given to Nevada by the U.S. Congress. This area became Clark County, and the southern part of Lincoln and Nye counties in Nevada.
There is little chance someone as far away as Nevada would take the trouble to go to New Mexico to conduct their county business. It is unlikely any records of people living in Nevada are actually found in Taos County records.
