I have never heard of the 13 society, although from looking at the site and other information I have gathered over time there are many references to
thirteen for many groups
Illuminati is a common one with the 13 bloodlines and the 13 degrees making a very good coinsidence, and possibilty of an offshoot.
There were original 13 colonies in America, and I believe there is supposed to be a group claiming descendance of the leaders of these colonies so
could be that.
A large number of societies with numbers as names tend to be intellectual groups like high IQ societies.
You will probably need a little more info before you will now where to look.
Bit of a catch 22 when you are first trying to fin out about something that is secret.
