Pocahontas 

Pocahontas was a Native American ambassador born around 1595. She was the daughter of Chief Powhatan, but rose to prominence through her involvement with the Jamestown colony settlers and her peace-making efforts between the two groups.

Despite the connection that the eponymous Disney movie shows between her and John Smith, it was actually John Rolfe who she ended up marrying. Though it does seem that she took some live-saving actions that spared John Smith. She sadly died at the age of 21.
