An undated advertisement for Omaha indicated the town was along the Missouri Pacific Railroad and "State Highway 65". It further indicated the school had 450 students. The advertisement described churches of every main denomination, that the town had electric and telephone service, a bank, canning factory, feed stores, a machine shop, mill, a modern garage, lumber yards and various types of stores. The ad claimed the town was started in 1878 after J.H. Middleton of Missouri came and began a general store.
