According to The Learning Kingdom, a site I subscribed a few years ago, Pocahontas was the daughter of Powhatan, chief of the Algonquian Indian tribes. In 1614, while a prisoner of English settlers in Jamestown, Pocahontas married colonist John Rolfe. Their marriage brought temporary peace between settlers and Native Americans. In 1616, Pocahontas went with Rolfe to England where she died, probably due to a respiratory illness. She was 22 years old.
Below is a picture of Pocahontas, quite different from what we know from the cartoon, don't you think?
