"The mystery of life isn't a problem to solve, but a reality to experience"
Henry's IV has a bonus of +1 card for Prot if he marries a French royal. Does that include Mary Q of Scots?
I do not see why not. The term French royals covers.. well all French royals. The only two French female royals Henry can marry are Mary Queen of Scots or Marguerite de Valois. The rules would have specified a Valois royal, or simply Marguerite de Valois if he would not have gotten the bonus from Mary Queen of Scots.
