What drives Carney’s History grade

On its age, its old homes and the National Register, Carney is more historic than 19% of U.S. towns, #182 of 261 in Maryland. Its age holds the grade up; its National Register listings pull it down.

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.

The story

How Carney came to be

From Wikipedia’s history of Carney.

Read it all →

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.
