I think it’s safe to assume that everyone from Fairytale is in Storybrooke. I personally doubt that anyone from any other magical lands, like Wonderland, ended up in Storybrooke, (which means I suspect Jefferson found a way back some time before the curse hit). But that dark cloud that came with the curse looked like it was tearing the whole land up well and good, so I’m thinking everyone in its path got swept up and plonked down in Maine.
