HistoryA character grade: shown, never part of Dimondale’s overall grade.
Few Michigan towns list much on the Register (a typical Michigan town has 0.0 per 10,000 residents, the U.S. 2.4), so Dimondale’s 0.0 sits below most of its state (32% of Michigan towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C to B−. The pre-1940 share is a Census survey estimate (±6.6 points). Two sources give 1856.

What stands out about Dimondale’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The Potawatomi originally had a permanent camp along the Grand River in the Dimondale area before white settlement began in the 1830s. Relations between white settlers (most of whom were from New York and New England) and the Potowatomie were generally cordial with local residents permanently deeding 10 acres (40,000 m2) of land near the river to the local Indians. The local band held the deed to the leased land until the Potowatomie were forced west by the Indian Removal Act.
