Welcome to the New Mexico USGenWeb Archives!
Gina Heffernan is the New Mexico Archives State File Manager. Please contact Gina if you have any questions or comments about the site.Keep in mind that much of the information on this site took place BEFORE the USA acquired this land in 1848. For much of this information there were only TWO "counties" - Santa Fe and Bernalillo. Everything east of the Rio Grande belonged to Texas from 1836 until it became a state. The original nine counties recognized in 1852 were Bernalillo, Dona Ana, Rio Arriba, San Miguel, Santa Ana, Santa Fe, Socorro, Taos and Valencia. About half of the territory became the Arizona Territory in 1863 and Santa Ana was annexed to Bernalillo in 1876. The other 25 counties were created between 1852 and 1950. There are two other areas referenced on map/census records, Mesilla and Arizona County. Mesilla was a large area in the southwest encompassing parts of Doña Ana, Grant, Hidalgo, Luna and Sierra but the location of "Arizona County" from the 1860 census is not known to me, unless it was part of what is now Arizona.
