WHAT A SENTENCE:
“Margaret had formerly expressed her disapproval and concern at her granddaughter being married too young, but as the Queen of Scots was approaching her fourteenth birthday—generally considered to be a more acceptable age for consummation—there is no evidence that she was unhappy at the king‘s decision to send his daughter north at this time.“
(That's the granddaughter in the image, roughly 13 at the time of the portrait.)
