What is "chichesters"

The Chichesters were an early Five Points street gang during the mid 19th century in New York. The gang began stealing from stores and warehouses and selling the stolen goods to local fences in the 1820s, later becoming involved in illegal gambling and robbery. An ally of the Dead Rabbits against the Bowery Boys, the Chichesters maintained between 50 to 100 members lasting for more than 50 years before being absorbed by the Whyos, much like many of the early gangs, following the American Civil War in 1865.
