What was the fate of Pocahontas after her marriage to John Rolfe?

After her marriage to John Rolfe in 1614, Pocahontas converted to Christianity and adopted the English name "Rebecca". She traveled to England with Rolfe and their young son, Thomas, in 1616 as part of a publicity campaign to promote the Virginia Colony. She was presented at the English court and became a celebrity, meeting King James I and Queen Anne. However, Pocahontas fell ill and died in March 1617 at the age of approximately 22. She was buried in the churchyard of St. George's Church in Gravesend, Kent, England.
