MCHS has a list of the County’s Post Offices and Postmasters,complied in 1990 by the amazing volunteer and museum curator Marj Miller (1923-2017). The source is “Record Group Description 028 Postal Service Record of Appointment of Postmasters for Montgomery County, Missouri page 658 and Site location file R25/2716 Box 376.” Information after 1960 may have come from other sources. An unsubstantiated and undated newspaper article claims that “In 1894 Montgomery County became the first county in the US where the PO tired out its newfangled Rural Free Delivery [RFD] services.”
