Legitimacy of Mary Queen of Scots

It is interesting to see that today, 10 May 2018, The Scotsman (p. 3) has an astonishing scoop: James V was not the father of Mary Queen of Scots, but instead it was Murdo Mackenzie! Ilona Amos has written that Fairburn Tower “was built in 1545 for Murdo Mackenzie, a close aide of King James V and father of Mary Queen of Scots.” Given that her current Majesty’s right to the throne derives from the legitimacy of Mary, Queen of Scots as great-grandmother of Sophia, Electress of Hanover, this revelation potentially rocks the foundation of the throne. Could this be a treasonous allegation? Or is it simply poor editing?
