Elizabeth of York
From Tardis Wiki, the free Doctor Who reference
Elizabeth 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 and was the mother of Henry VIII. (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.
