Santa Cruz County Border Heritage

Santa Cruz County shares a border with Mexico. This geographic position shaped local family histories in unique ways. Many families have roots on both sides of the border. Spanish colonial records, Mexican government documents, and American territorial records may all be relevant to your Santa Cruz County genealogy research.

The town of Nogales is actually two cities with the same name split by the international boundary. Families moved back and forth across the border before modern restrictions existed. Some ancestors appear in both American and Mexican records. Church records from Catholic parishes in the region often predate civil registration on both sides of the border and can help fill gaps in your family tree.

Ranching and mining brought many settlers to Santa Cruz County in the 1800s. The Santa Rita Mountains and surrounding valleys supported cattle operations and mining claims. Land records and mining claims in the Recorder's office document these activities and the families involved. If your ancestors worked in these industries, county property records may reveal their story.
