The story

How Sayville came to be

From Wikipedia’s history of Sayville.

Read it all →

The earliest known inhabitants of Sayville were the Secatogue tribe of the Algonquian peoples.

Sayville was founded by John Edwards (b. 1738) of East Hampton, New York. He built his home, the first in Sayville, in 1761, located at what is now the northwest corner of Foster Avenue and Edwards Street. The house was destroyed by fire in March 1913. Another man, John Greene, settled what is now known as West Sayville in 1767.

The community had no formal name until 1838 when residents gathered to choose a name for their post office, which had opened on March 22, 1837.
