I want to know the names of spy rings beyond the Culper spy ring, that operated during the American Revolutionary War. Beyond just the name, it would be helpful to know where the spies operated as well (if such information is available). Providing outside sources is a big plus, but not necessary.
The names I am looking for are specific the names of the rings of spies, not the individual spies. I have seen this information on a website before but I cannot locate it again.
