What drives Zelienople’s History grade
On its age, its old homes and the National Register, Zelienople is more historic than 80% of U.S. towns, #326 of 1,035 in Pennsylvania. All 3 inputs are above most U.S. towns; its age ranks highest and its National Register listings lowest.
A−
HistoryA character grade: shown, never part of Zelienople’s overall grade.
Pennsylvania towns list about as much on the Register as the country (a typical Pennsylvania town has 2.1 per 10,000 residents, the U.S. 2.4), so Zelienople’s 2.6 sits near the middle of its state (60% of Pennsylvania towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B+ to A−. The pre-1940 share is a Census survey estimate (±8.3 points). Two sources give 1802.

Zelienople was named for the eldest daughter of Baron Dettmar Basse (1762–1836), whose chosen name was Zelie (her given name was Fredericka) which she named herself after her favorite doll. Baron Basse arrived in 1802 from Frankfurt am Main, Germany, and purchased a tract of 10,000 acres (40 km2) of land in Butler and Beaver counties.
He proceeded to lay out a village and build his residence, a three-story castle complete with towers, turrets and battlements, named "The Bassenheim." At the time, Zelie was betrothed to Philip Louis Passavant and was still in Germany. Extensive preparations were made by Basse to establish the new home and town in America and prepare it for his daughter's arrival in September 1807.
