Ha. :) Rapunzel would be an unlikely inspiration in my opinion, though there could be a connection to other similar stories from the brother's Grimm (many of the Grimm's Fairy Tales have similar points of trapped princesses, etc.). The relationship between Elizabeth and Songbird sounds really interesting.
