Looks like at least some of the Houses (like House of Heartshaven) were affiliated with a given chapter (since it's called a Prydonian house).

Also, there's the question whether all of the Gallifreyan Houses are "Great".

But yeah, between NAs, EDAs and Big Finish, it's probably quite a convoluted mess.
