HistoryA character grade: shown, never part of Jefferson Township’s overall grade.
Indiana towns list more on the Register than most of the country (a typical Indiana town has 7.9 per 10,000 residents, the U.S. 2.4), so Jefferson Township’s 0.0 sits below most of its state (22% of Indiana towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share is a Census survey estimate (±13.1 points).

What stands out about Jefferson Township’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Jefferson was one of the earliest settlements in Clinton County, being laid out and platted before 1829 and situated in the most thickly settled part of the county at that point. It early on had a post office, which handled mail bi-weekly, and a store operated by Abner Baker and Aaron Southard which sold supplies both to the early pioneers and to the Indians.
When Clinton County organized in 1830, local landowners led by Abner Baker lobbied for Jefferson to be chosen as the county seat, but its non-central location worked against it. John Pence offered 60 acres (240,000 m2) of land and $100 for the establishment of the seat at Frankfort, and the commissioners appointed to select the site accepted.
Nothing in the archives for these yearsWeddings on Main Street, storms, parades, school pictures, the old store. If it’s in your family album, it belongs here.
