George Robert “Bob” Anderson (1847?-1886?) was an early settler in Southern Nevada. He is best known for being the business partner of James Bernard Wilson. On January 31, 1875, they filed the deed to 320 acres located twenty-four miles west of Las Vegas, Nevada at the base of Sand Mountain in Cottonwood Valley. The property formerly known as ‘Williams Ranch’ or ‘Williams Homestead’ was renamed Sandstone Ranch. There they established a working cattle ranch and a goods delivery service.
