Weaubleau Creek: The creek enters Tyler Township from Polk County. It flows into southwest Montgomery and then into St. Clair County before joining the Osage River.[2]
Bledsoe: A post office functional in 1867–1868, in southern Montgomery. It was named after Bledsoe Montgomery, a son of judge Joseph C. Montgomery.[2] When Montgomery Township gave up eastern sections in the formation of western Wheatland Township in 1881, the village of Wheatland located three miles to its south became the site of the post office servicing Bledsoe's old postal customers.[2]
Quincy: A post office functional in 1867–1868 and 1886, in central Montgomery. The area was settled in 1833 and platted by Isaac M. Cruce in 1848. It was most likely named after John Quincy Adams, the 6th president of the United States. The area was called ″Judy's Gap″ before it was platted since a blacksmith named Samuel Judy had set up a shop there. The ″Gap″ comes from the opening between the two prairies in the area; Hogle Creek Prairie and 25-Mile Prairie.[2]
