Assuming that all lineages are correct and haven't been tampered with, there seems to be a great number of Royals who are Haplogroup G2a. This comes obviously from the testing of King Louis XVI who can trace his ancestry back to Robert of Hesbaye, some of these other famous individuals include Afonso Henriques [King of Portugal], Hugh Capet, Juan Carlos I [Current King of Spain]. This would make all these rulers haplogroup G, does anyone else know any other royals that can trace their Patrilineal lines to Robert of Hesbaye. This line clearly founded much of the French, Spanish and Portuguese royal lines.
