Elizabeth of York (TV: The Coach with the Dragon Tattoo) was the oldest child of Edward IV of England and Elizabeth Woodville and thus the older sibling of the so-called "Princes in the Tower". (AUDIO: The Kingmaker)
She later married Henry VII to unite the York family and the Tudors after they fought in the Battle of Bosworth. She later gave birth to Henry VIII, Arthur Tudor, Margaret Tudor and Mary Tudor. (TV: The Coach with the Dragon Tattoo)
Behind the scenes
The Kingmaker doesn't actually use the full title "Elizabeth of York", but offers no better term than her real world designation.
