Santa Cruz County, Arizona Genealogy

Santa Cruz County lies directly south of Tucson and Pima Counties. 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.

A river runs north out of Mexico towards Tucson, also named the Santa Cruz.

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