History Around 1852, the first buildings had been erected within the town, including living quarters for the rail-men, the freight depot, and passenger station. This same year, the house for Gr. W. Goodwell, Wenona's station agent and first postmaster, was completed. Along with the post office, in June of 1854, the Presbyterian Church was set up.
