That's Mary I of England, or Mary Tudor. (The question sheet probably should have made this clear, but didn't.)
Philip II had four wives, of whom Mary was the second. The first was Maria Manuela of Portugal; they married in 1543, but she died 20 months later (in July 1545), four days after giving birth to a son. (The son, Don Carlos, died in 1568 – thirty years before his father.)
Mary Tudor died in 1558. Philip underwent two further marriages; his third wife, Elizabeth of Valois, also died in 1568. In 1580 Philip married his niece Anna of Austria. They had three children, but Anna died shortly after giving birth to the third, who went on to succeed his father as Philip III of Spain.
Mary II of England and Scotland was obliged to marry her first cousin, Prince William of Orange, who became William III of England when she succeeded her father, James II.
The prevarication of the Scottish clans (and particularly the MacDonalds of Glencoe) in recoginsing the Protestant William III of England as their monarch was ostensibly the excuse for the Massacre of Glencoe, which (as we've already seen) took place in 1692.
The other Queen Mary – Mary, Queen of Scots – married lots of people, but Philip II of Spain wasn't one of them.
