HistoryA character grade: shown, never part of Rockwall’s overall grade.
Few Texas towns list much on the Register (a typical Texas town has 0.0 per 10,000 residents, the U.S. 2.4), so Rockwall’s 0.2 sits above most of its state (69% of Texas towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D to C+. The pre-1940 share (±0.4 points) is firm at this size. The founding year is the first post office, not a stated founding date.

The association of Paleo-Indian artifacts with extinct Pleistocene mammal remains in various archeological sites within the Texas Prairie-Savannah Region of eastern North Central Texas, including a site in Collin County, and Clovis points recovered from the Brushy Creek Clovis Site in Hunt County demonstrates that the Rockwall region was occupied by prehistoric Native American cultures at least as far back as 13,500 to 13,000 years ago. More recently, the Rockwall region was occupied by Caddo Indians. Creek Indians moved to the area in the early 19th century. In 1925, Byron Khun de Prorok claimed that the wall was built by a prehistoric race, though this has been widely dismissed .
