Per FAG contributors #46963612 "Carrie and Allen", Aug. 7, 2014:
"George Cornett arrived in Central Oregon in 1881 when he was 23 years old. He became involved in the stagecoach business, eventually covering 500 miles of roads and owning 360 horses and 100 vehicles. In 1910, he started using automobiles, acquiring a fleet of 13 cars. He was also involved in sheep raising.

In 1907, he founded "Clifton and Cornett", a general merchandise business. After buying out his partner, he reorganized as "Cornett and Company". The building was located on the southwest corner of Main Street and 4th Street until the Prineville Fire destroyed it in 1922. Afterwards, he rebuilt the building, which is still extant.

In 1920 he bought a sawmill on Grizzly and later that year shipped the first load of lumber to travel over the City of Prineville Railroad, built when the main railroad line bypassed the city.

His home was built in 1912 and is still standing (390 W. 1st Street). From 1940 to 1950 this building housed the Prineville General Hospital.

Cornett died in 1932 of a heart attack."

"The address listed as the Cornett Residence, which was the old hospital, is incorrect. The reason I know this, is that my family lived in his first home which sits on the corner of 1st and SW Deer St, and that address was 390 West First St. I lived in that home and had that address from the time I was 2, until the time I was 21, with my parents, Lawrence A & Frances V Randle.The 390 W. First St address is now a different address and houses a business. The old hospital sits right next to where 390 W First St building sat."
