Neshannock Potato

Washington Township, Lawrence County, Pennsylvania

Marker Inscription

The once widely-known and choice variety originated just west of here, on a farm occupied by John Gilkey, 1798-1826. A brother, James, was fellow-worker. Their potato was also called Mercer or Gilkey.

The Story

On a farm just west of here, worked by John Gilkey between 1798 and 1826 with the help of his brother James, a new and prized variety of potato took root. Known as the Neshannock — and also called the Mercer or Gilkey — it became one of the most widely grown and admired potatoes of early nineteenth-century America, praised for its quality on tables across the young nation. It was a homegrown agricultural success story born on the western Pennsylvania frontier.

Why it matters

The Neshannock potato shows how ordinary farmers drove early American agricultural innovation, spreading a locally bred variety to fields far beyond its Pennsylvania birthplace.

Johnston Tavern

Springfield Township, PA · est. 1948

In the decades after statehood, taverns like Arthur Johnston's were the gas stations, inns, and news exchanges of the American road. Licensed in 1827 with the present stone-and-timber building raised in 1831, this house fed and lodged travelers moving along the Pittsburgh-Mercer road in western Pennsylvania. Its fortunes were tied to the nearby Springfield Furnace, an iron works that fired up after 1837 and drew traffic to the crossroads.

Mercer County

Mercer, PA · est. 1983

Mercer County was established in 1800 from Allegheny County when this corner of western Pennsylvania was still thinly settled frontier, home to just over three thousand people. It honors General Hugh Mercer, the Revolutionary War officer mortally wounded at the Battle of Princeton in 1777. Rich in iron ore and coal, the region became an early center of industry, and the county seat of Mercer was incorporated in 1814.

Lawrence County

New Castle, PA · est. 1982

Created in 1849 from parts of Beaver and Mercer counties, Lawrence County honors Capt. James Lawrence, the naval hero of the War of 1812 remembered for the dying cry "Don't give up the ship." Its county seat, New Castle, had been laid out decades earlier, but the town's real boom came around the turn of the twentieth century, when it exploded as a center of the American tin-plate industry. For a generation it ranked among the fastest-growing cities in the nation.

Warner Brothers' First Theater

New Castle, PA · est. 1994

Long before Hollywood, the Warner brothers got their start in New Castle, where in 1906–07 Harry, Sam, and Albert Warner ran a tiny nickel theater seating just 99 people who paid five cents to watch three short films. That humble storefront was the seed of an empire: sixteen years later, Warner Bros. Pictures was founded and would help define the American movie industry.
