Bolivar Roberts Bolivar Roberts, Division Superintendent at Carson City, was a native of Winchester, Stark County, Illinois. He left home at the age of nineteen and migrated to the Utah Territory. In 1852 he moved to Placerville, California, with his father and brother and took up mining.

Due to the proximity of General Agent Finney, who exercised primary supervision over the full western section, Robert's authority and scope of duty were more limited than other division superintendents on the route. His duties concerned the physical aspects of the operation, the care of men and stock which Finney supplied.

When the express came to an end. Roberts took up mining in Virginia City, Nevada, then in Wyoming, and later near Salt Lake City. After 1870, he farmed, raised stock and opened a drug store which his son managed. By 1888, when 57, Roberts was described as a "man of considerable means."
