What drives Carney’s History grade

C−
HistoryA character grade: shown, never part of Carney’s overall grade.
Few Maryland towns list much on the Register (a typical Maryland town has 0.9 per 10,000 residents, the U.S. 2.4), so Carney’s 0.0 sits below most of its state (20% of Maryland 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 (±1.3 points) is firm at this size. The founding year is the first post office, not a stated founding date.

What stands out about Carney’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
In 1880, Thomas Carney immigrated to the United States from Ireland and settled in Texas, Maryland. Soon after his arrival, he married the former Mary McDermot and bought forty and one-half acres on the southeast side of the Baltimore and Harford Turnpike.
Several years later (circa 1885), the Carney family moved to what is now Harford and Joppa roads, where Thomas Carney opened a general store which is believed to have served as the Eight Mile House on the turnpike. The store was located on the site presently occupied by the Das Bierhalle Restaurant. In the 1880s and 1890s, the store also served as the Carney family home.
The Carney post office opened in 1888, the earliest record of the town by name (U.S. post office records).
