Cinderella had two sisters

Esmeralda and Jacobina have a younger sister Cindy. Alda is plain, but a musician with good taste. Jac is fat, placid, and quite insecure. But Cindy is pretty, blonde, blue-eyed, and popular. Alda is, in truth, the real Cinderella of the story. Besides being the focal point of the narrative, she does the kitchen work and generally looks after the others.
