What drives Chapin’s History grade
On its age, its old homes and the National Register, Chapin is more historic than 43% of U.S. towns. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.
C+
HistoryA character grade: shown, never part of Chapin’s overall grade.
South Carolina towns list more on the Register than most of the country (a typical South Carolina town has 3.2 per 10,000 residents, the U.S. 2.4), so Chapin’s 93.3 sits above most of its state (84% of South Carolina towns have fewer) while its 13 historic buildings outnumber those of 77% 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 (±1.8 points) is firm at this size. The founding year is the first post office, not a stated founding date.

What stands out about Chapin’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Chapin was named after Martin Chapin in 1889. After he and Laura Anne Benjamin were married on June 16, 1850, the couple moved down South because of Martin's health (a lung condition). The Chapins were living in Columbia when Martin's doctor suggested he to move to the Piney Woods area. Over the years, Chapin bought 4,218 acres (1,707 ha) of land in this area. He built a home in Piney Woods, and later a hotel in the 1880s along the new rail line that ran from Columbia to Laurens, the Columbia, Newberry and Laurens Railroad. The railroad provided a way to trade and transport goods to the capital city. Cotton and the lumber industry were flourishing with the railroad providing transportation. After Martin's death on August 31, 1894, Laura Chapin sold their home and moved into the Chapin hotel.
The Chapin post office opened in 1888, the earliest record of the town by name (U.S. post office records).
