HistoryA character grade: shown, never part of Lloyd Harbor’s overall grade.
New York towns list more on the Register than most of the country (a typical New York town has 12.3 per 10,000 residents, the U.S. 2.4), so Lloyd Harbor’s 107 sits above most of its state (76% of New York towns have fewer) while its 38 historic buildings outnumber those of 83% 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 is a Census survey estimate (±4.7 points). Two sources give 1926.

What stands out about Lloyd Harbor’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
In 1654, the Matinecock Native Americans sold 3,000 acres (12 km2) of what is now called Lloyd Neck to English settlers from Oyster Bay. The Matinecock referred to the region as Caumsett ("place by sharp rock"). In 1676, James Lloyd acquired the neck, which was then taken over by his son Henry. Henry Lloyd farmed the land and erected a house, which still survives in Caumsett State Park. After his death in 1763, his son Joseph built the Joseph Lloyd Manor House, which he was forced to abandon by the British during the Revolutionary War. The British built several fortifications in the neck, including Fort Franklin. Henry Lloyd IV was the last Lloyd to own the estate, in 1841. In the 1880s, it became a stop for steamboats coming from New York City, bringing tourists and wealthy New Yorkers.
