HistoryA character grade: shown, never part of Heath’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 Heath’s 0.0 sits below most of its state (34% of Texas 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 D to C. The pre-1940 share (±0.9 points) is firm at this size. The founding year is the first post office, not a stated founding date.

What stands out about Heath’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Heath, Texas, is a city in southwestern Rockwall County, Texas, located along Farm Road 740, approximately seven miles south of Rockwall. The community was named after John O. Heath, one of the area’s earliest settlers in 1846. Originally known as Black Hill due to its dark soil, the settlement established the first post office in what is now Rockwall County in 1849. After the post office moved to Rockwall in 1854, the community was renamed Willow Springs until 1886, when it became Heath and briefly regained a post office, which operated until 1906.
The Heath post office opened in 1886, the earliest record of the town by name (U.S. post office records).
