Santa Cruz County lies directly south of Tucson in Pima County.  The town of Nogales is a major border crossing between the United States and Mexico, and is part of a 'twin border city' situation. Nogales is also the county seat.

The Santa Cruz river runs north out of Mexico towards Tucson.

The historic Catholic mission near Tubac on I-19 was significant in the history of the area. However, any records that were produced when this was an active parish were not kept there, but may be in the Diocese in Tucson. Other missions are also nearby, mainly San Xavier which is in Pima County closer to Tucson.

  • Until 1821 -  New Spain controlled land that later would become Arizona. Some records of early settlers may have been sent to an archives in Seville, Spain, or to archives in Mexico City.
  • In 1821 - Mexico obtained jurisdiction over the land that later would become Santa Cruz County, Arizona. Records of this period may have been sent to archives in Mexico City.
  • 8 June 1854 - all Gadsden Purchase land south of the Gila River was added to the already existing Doña Ana County, New Mexico Territory.[2] [3] This included land that later became Santa Cruz County, Arizona. Records during this time period may have been sent to the Doña Ana County, New Mexico courthouse.
  • 24 February 1863 - Arizona was created from the western half of New Mexico Territory. All previous counties were dissolved, and eventually four new counties were formed in the new Arizona Territory.

Parent County

  • 15 March 1899 - Santa Cruz County was created  from Pima and Cochise Counties.
    County seat: Nogales [4]
