History Timeline


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