HistoryA character grade: shown, never part of Bethany Beach’s overall grade.
Delaware towns list more on the Register than most of the country (a typical Delaware town has 29.4 per 10,000 residents, the U.S. 2.4), so Bethany Beach’s 11.0 sits near the middle of its state (42% of Delaware 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 D− to C−. The pre-1940 share (±0.7 points) is firm at this size. Two sources give 1901.

There is a lack of evidence of Native American activity in the Bethany Beach area. Prior to the arrival of European settlers in North America, Native American settlements appear to have been limited to the area north of the Indian River, north of what is now Bethany Beach; even after Europeans pushed the Native Americans—mostly Nanticokes—out of their coastal settlements in the mid-17th century, the Native Americans moved west to settle around Oak Orchard, Delaware, and in the Millsboro, Delaware, area rather than south toward what would become Bethany Beach. However, Native Americans are known to have visited the bays and rivers of the Atlantic coast of Delaware during the summer to fish, and it is possible that this included visits to the Bethany Beach area.
In 1901, according to Wikidata. Bethany Beach’s post office opened in 1905, and the census of 1910 counted 56 people here.
