For example, goblins, faeries, trolls, ogres, gargoyles, elves, and nymphs all came from the same place, originating somewhere near what we know today as Ireland. Of course that was when all the continents were one big lump of earth so I'm not sure pinpointing a modern country really means much.
How can a squat, hairy, yellow-toothed goblin compare to the legendary beauty of a nymph you ask? It's in what's underneath. Never let the outside of a Super fool you. Many are made by design to lure their prey into a false sense of complasancy. Now, I am by no means saying they are all bad or good for that matter. They are what they are and as civilized as many have become, they still have certain drives hardwired into their systems.
Demons and sprites are trickier. Some theorize that most Supers of today are some combination of demon mating with human or faery. Truthfully though, I've never met a demon that seemed remotely interested in getting it on with a Normal (human being), so I have my doubts. No these creatures are more spirit than corporeal body and can exist not only in our own world physically but in what many of their kind fondly refer to as The Oven. Yes that's Hell. But it may not be Hell in the way we think of it through religion. It may be an alternate dimension entirely, but that's a story for a different time.
Now, vampires, werewolves, shapeshifters and merpeople are another can of worms. Sometimes it behooves us to simply accept that there are things out there that while entirely natural have found their own way on the road of evolution. What I can tell you is that these Supers have human or animal form (or the ability to take on or mimic human or animal form) so that they can blend in much like a chameleon. Whereas the other creatures in this blog overwhelmingly have to resort to magic to do the same.
