It seems from this that there is a Y-chromosome mismatch between Richard III (as confirmed by his mtDNA, age, scoliosis etc), and the present Duke of Beaufort.
There are various possibilities and our piece “A genealogical mystery deepens” outlined one – that Sir Hugh Swynford fathered the first “Beaufort”, making the Dukes of Somerset, Beaufort and “Tudors” his descendants.
There is one interpretational error in the (very long) article, however. Any break between Edward III and Edward IV/ Richard III would not invalidate their claim because their father’s maternal line was senior to the Lancastrians. The real Lancastrians would not be affected by our hypothesis which is, of course, one of many and can be tested in ways we have made clear.
Now we have the irony of a broken DNA link being described by a broken weblink in the Daily Mail
