"When, however, a post office was first established there, it was named Lost Branch, for the nearby creek. In 1875, however, on the 17th of May, it was resurveyed and platted by Surveyor John C. Downey for John C. Wells and the other proprietors, and was then renamed Olney. The post office of Lost Branch was discontinued in 1877 and Olney established in its place." ~ Postal Guide: and History of Lincoln County, Goodspeed, pages 237, 442
