Rapunzel by The Brothers Grimm

Brothers Grimm's fairy tales are recognized because they are dedicated to children. The Rapunzel story is one of the most important and for this reason the Brothers Grimms decided to adapt the story with few diferences. 

Taken from: http://www.encuentos.com/cuentos-en-ingles/rapunzel-cuentos-infantiles-clasicos-en-ingles-literatura/

one difference is that Rapunzel's parents wanted very much to have children until they were finally able to conceive of Rapunzel, on the other hand, the old story tells that after the disease Rapunzel's mother she was pregnant. Another difference is that Rapunzel's mother during pregnancy had a great craving to eat the fruits of the next garden, and the classic story tells that Rapunzel's mother was ill and the only way to heal it was eating these fruits. Also in the story adapted by the Brothers Grimm, Rapunzel was taken to a desert where she had two children with the prince, while in the classic tale Rapunzel didn't had children and was carried to a lonely forest.
