as there are many Non Paternal events in Royal Lines i do not think the Y DNA of Richard III belongs here as there is no one of the G-P287 Haplogroup in the Warren YDNA Project just an observation https://www.familytreedna.com/public/warren/default.aspx?section=ycolorized

he is also my great-grandfather and I do have DNA done but autosomal, in fact all the magna carta surities are my great grandfathers from 22-26th. can you check my DNA with them to see if there is a common match ?FTDNA 594369 T371219

Robin, what am I missing? The link you provided has a link to the article giving the results of the DNA testing of Patrice de Warren, who traced his line to King Richard III through Geoffrey, Count of Anjou. Patrice's Y-chromosome doesn't match Richard III or the Somerset line, indicating another false paternity...

To the best of my knowledge, this line is definitely NOT proven by DNA. Please don't change it without bringing up a discussion on G2G first, & be sure to tag any G2G posts with both EuroAristo and Magna Carta. Thanks.

Here's some interesting work, which indicates that the modern de Warrene line is genetically matched to Richard III, via Geoffery d'Anjou. Meaning... yes. There is data to indicate, though not conclusively; within reasonable margins of error, that the de Warrene line is confirmed. - http://www.iflscience.com/technology/dna-tests-uncover-more-evidence-infidelity-richard-iiis-family-tree Make sure to look at the connection charts toward the bottom.

WAIT! I assumed heredity based on Surname. Wrong, wrong, WRONG of me to do in this era of Euro-hostory! William the Conqueror Was the first Earl, but was the grandfather of William's WIFE. He took HER name! Ah, the good old days.

From what I can tell... yes? The research I've been reading indicates that a reasonably accurate summation of Williams y DNA has been assessed, and within margin of error parameters, if you have a minimum number of common markers, you have the potential of being related. Here is the most current published scientific report on the subject from OriginsDNA: http://originsdna.blogspot.com/2014/04/conquering-williams-dna.html

So... the "confirmed by DNA" was intentional? I'm not real swift when it comes to DNA, and I'm totally lost in trying to imagine how someone born in the 1100s could have their relationship with their parents as "DNA confirmed." Heck, my eyes glazed over just reading Robin's post.
