HistoryA character grade: shown, never part of Gahanna’s overall grade.
Ohio towns list about as much on the Register as the country (a typical Ohio town has 2.9 per 10,000 residents, the U.S. 2.4), so Gahanna’s 1.1 sits near the middle of its state (50% of Ohio towns have fewer) while its 4 historic buildings outnumber those of 68% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C to B+. The pre-1940 share (±0.7 points) is firm at this size. The founding year is the first post office, not a stated founding date.

What stands out about Gahanna’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Gahanna was founded along the Big Walnut Creek in 1849 by John Clark of Ross County from 800 acres (320 ha) of land that his father, Joseph Clark, had purchased from Governor Worthington in 1814. Clark named his property the Gahanna Plantation, from which the City of Gahanna derives its name. The name Gahanna is derived from a Native American word for three creeks joining into one and is the former name of the Big Walnut Creek. The City of Gahanna's Official Seal refers to this confluence of three creeks with the inscription "Three In One".

In 1848-9 Messrs. John Clark, Esquire, and Jesse Baughman, Esquire, living in close proximity, were mutually inspired to found a town, which, mayhap, might sometime grow into a city. Squire Clark, on one side of the dividing line, laid out and had platted a town bearing the name of Gahanna. Squire Baughman proceeded to lay out and have platted a town which he christened Bridgeport, and it became a race as to which name should survive— it is Gahanna now. In 1849 Gahanna postoffice was established and it still retains a place on the map. Thomas Young was the first postmaster
