Andrew J. Weatherby was the property owner and postmaster in July 1879 and the place became known by his name.
Historical Significance of Weatherby
C. W. Durkee established the Express Ranch post office on April 21, 1865, in Baker County during the heady days of the mining excitement. It got its name because it was a stop for stagecoaches or expresses as they were also called in those days. In July 1879, this office was moved ten miles to the southeast to the Weatherby place, where Andrew J. Weatherby was the postmaster and changed the name to Weatherby.
The Weatherby office continued in operation until Feb. 1920.
