Dona Ana County, Arizona Genealogy

''United States Arizona Dona Ana County, AZ''

Dona Ana County was proposed in 1860 for the self-declared Arizona Territory and a territorial government was created. But the US congress rejected the idea. However if a county government was set up, some county records may have been created. Then in 1861, the Arizona Territory chose to be part of the Confederate States of America. But when Union forces took over in 1862, any county government still existing would have been shut down. The location of any county records, if they exist, has yet to be discovered.


 * 5 Apr 1860 - An unofficial convention held in Tucson declared the creation of the Territory of Arizona from the southern half of New Mexico Territory below 34 degrees north latitude and proposed 4 counties for the new territory: Castle Dome, Ewell, Mesilla, and Dona Ana. They also created a provisional constitution and established a government.  But the US Congress rejected the idea of Arizona becoming a territory, just as they had eight times before. So the proposed new territory was never officially created. However this time was different, because a government had been created for the intended Arizona Territory.
