I tell a lie about the schools, one got funded: "In 2005, however, the Stamford Hill Yesodey Hatorah Senior Girls' School achieved voluntary-aided status."
It is all very interesting, and if you live in an area where you sometimes see people walking around in unusual clothes you do ask / read up on it!
The people we have a lot near us who are christian are exclusive brethren
There is info about the community in stamford hill here and of course google is your friend!
I know more about the brethren because I knew some at school - they aren't allowed to watch TV, read newspapers or anything, I think they opened their own schools and separated off as you don't see them around so much any more.
It is all very interesting and to my eyes these groups all seem to have similar things in common irrespective of the "flavour" of the religion iyswim
