There's been another study of the YDNA (direct paternal line; ie father's father's father, etc.) of the Bourbon dynasty, taking samples from three LIVING male Bourbons (Prince Axel of Bourbon-Parma, Prince Henri-Sixte of Bourbon-Parma, and Prince João of Orleans-Braganza).
A couple years ago, YDNA was also taken from blood believed to belong to Louis XVI of France (Marie Antoinette's husband) and compared to DNA taken from a head believed to be that of Henri IV of France, his ancestor. The results were positive. Both YDNA samples came back as haplogroup G2b.
But those samples don't match the Bourbon samples from the three living gentlemen!
Princes Axel, Henri-Sixte, and João are all in haplogroup R1b, which is in no way identical to G2b. Now scientists are saying the samples from Louis XVI and Henri IV must be misidentified, they can't belong to the kings. But then how did they match each other?? G2a is a fairly rare Y-chromosome haplogroup. It'd be a mighty big coincidink for two random misidentified DNA samples to match each other with such a rare haplogroup!
What I'm wondering is if its not just as likely that there was a 'non-paternity event', so to speak, in the intervening generations which results in the three living princes not having the same YDNA as their legal ancestors.
