Hunchbacks and wicked witches

Another query to put to you all:  I've been asked to name some folk tales that feature people with what we would call today disabilities:  blind, deaf, lame, missing parts, etc.  I don't know what definition of "folk tale" is in play, so any and all popular (but originally oral) tales (and some written but effectually oral, I suppose, like Beauty and the Beast or Thumbelina) would be passed on.
