General Francisco "Pancho Villa"
was rumored to have regularly crossed the Nogales border and when he had, would hide in secret rooms or closets in some of the prestigious homes on Crawford Street.
The man who restored order, sort of...in 1853, a former U.S. Cavalry soldier, Pete Kitchen, established a ranch and fortified stronghold 5 miles north of present day Nogales, Sonora along fertile Portrero Creek. He recruited a group of 28 Opata Indians from Sonora Mexico to help build the structures and act as "Kitchen's Army" guarding the area 24 hours a day. Eventually, Kitchen tired of the settled life and sold his ranch. Today it's a restaurant.
In 1880, Jacob Isaacson, a Russian immigrant, built a trading post, called Isaacson, which later became Nogales.
