What I do suspect is that some Sidhe do know about Merlin, but the general public don't. Maybe, the older Sidhe might know something about Emrys while the younger ones, such as Sophia, her father and to a certain extent, the Sidhe elder, may be completely oblivious, even though it is difficult to determine their exact ages. It's kind of like how we were wondering why Nimueh was able to know who Merlin was while Morgause died not knowing at all, despite the fact that both of them were supposedly sorceresses of the old religion.
