Pierre Terrail, lord of Bayard (1476 (?)-1524), commonly known as Chevalier de Bayard, was a French nobleman that remained remembered as "the greatest knight". He was known for many military exploits (such as single-handed defense of Garigliano bridge aganist 200 Spaniards), as well as for humanity and honor in times when mass war crimes were being commited by mercenary companies.

Y-DNA: I2a2a (I-M223)
mtDNA: H10e

There is one big mistake in the study (http://file.scirp.org/pdf/OJGen_2017033014592625.pdf) which contains his results:
The predicted Y-haplogroup I-M223 is equivalent to I2a2a, previously known as I2b1 of haplogroup I [8]. In fact one of us (G.L.) established that this haplogroup corresponds to the sub-clade S21/U106 of the major haplogroup R1bM269 [9]. In current European populations, this sub-clade shows a peak of S21 frequencies centred on Germany and surrounding areas (Figure 2); because of these particularities, it was named the “Germanic” Y-haplotype.

This is another example why "geneticists" should not be taken for granted, and why everything said by them should be double-checked. Heck, they declared I2a2a a subclade of R1b (!?), and put his final result in paper as R1b-U106. I'm sure this mistake wouldn't happen not even to the most amateur internet genotard.

So, even though Whit Atey's haplogroup predictor gave them I2a2a, they decided to put (for some "unknown" reason) R1b-U106 as his result in this study. Users from Anthrogenica also entered his STRs manually (available in the study) using Nevgen Y-DNA predictor, and got the same result (I2a2a): http://www.anthrogenica.com/showthread.php?10135-Y-Chromosomal-Profile-and-Mitochondrial-DNA-of-the-Chevalier-Bayard-(1476-1524

Nevgen Predictor says I2a2-M223 with 99.63% probability:

Haplogroup Probability Fitness
1 I2a2a M223 99.63 16.88
2 E1b1b 0.19 10.8
3 G1-M342 0.06 9.99

Nevgen is IMO more accurate than Whit Athley's Predictor.

Exactly! It seems that they just didn't like the I2a result?

Yep, both predictors say the same.
I just don't know how they allowed such a mistake to happen... like, how they could connect I2a2a to R1b? :P This is the biggest fail I've seen so far in studies.

Of course it is, it's made by Serbs :D
