Castle Dome County, Arizona Genealogy

Castle Dome County was proposed in 1860 for a self-declared Arizona Territory. Four counties were proposed, Castle Dome, Dona Ana, Ewell, and Mesilla. A territorial government was created and maybe county governments. If governments were created, then records exist.

This Arizona territory requested recognition by the United States, but was rejected by Congress. So in 1861, they chose to be part of the Confederate States of America. However when Union forces took over in mid-1862, any governments still existing were shut down. The location for any county records 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.
