 * 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.

A few of the earliest settlers in what is now southern Colorado may have conducted their county business in Taos via the Santa Fe Trail. For records of residents in what later became southern Colorado from 1852 to 1861 check Taos County, New Mexico records. From 1 February 1860 to 1861 also check records of Mora County, New Mexico. After 1861 a part of New Mexico Territory was transferred to Colorado, and record keeping shifted to the appropriate Colorado counties.
