Nullifidan, heresiarch, latitudinarian-- Is there some database where I can find other obscure words describing "types" of people?

I only come across these really obscure words while reading. I really love the weight they carry. Do you know of any place where I can find more words of the same family? If not, do you know any other words like this? Please don’t say any words for specific phobias. I find those incredibly uninteresting :I

Thanks friends
