How sure. Graded on any two of the three inputs instead, the letter would still be C. The pre-1940 share is a Census survey estimate (±6.4 points). The founding year is the first post office, not a stated founding date.

John Sweeny settled nearby, and in 1835, purchased the original Imla Keep League from Varner and constructed a house on the site. The home, today the Sweeny Plantation, a Recorded Texas Historic Lan…
The Sweeny post office opened in 1895, the earliest record of the town by name (U.S. post office records).
