For several centuries, some historians and other writers have connected Sir Thomas More’s narrative of the murder of Edward IV’s sons to the bones found in 1674 and declared them to prove his case, even to the point of deluding Tanner and Wright in 1933 into calling the bones “Edward” and “Richard” before they even started. This theory has required its adherents to believe that More, who was five in 1483, was telling the absolute truth at first but suddenly switches to falsehood when he tells of the bones being disinterred and reburied somewhere else. Now, of course, modern medical interpretations of Tanner and Wright’s results (Carson, pp.214-32) express doubts as to the age, gender and number of individuals buried there whilst Carson herself (http://www.annettecarson.co.uk/357052362 and in the same chapter) notes the extreme depth of the burial, implying that it considerably pre-dated 1480-90, together with the evidence that “Edward” was likely to be mortally ill. The entire theory is becoming a colander and the probability of a real scientific investigation increases.
The Cairo residents, however, seem not to have given up. “Those may not be the actual bones and More’s second half may be accurate”, they claim, pointing us towards two small coffins found in Edward IV’s Windsor tomb in 1789 (http://www.stgeorges-windsor.org/archives/blog/?p=837). At first these were thought to belong to Mary and George, Duke of Bedford, Edward IV’s other children by Lady Grey, his “widow”, but these have subsequently (1810) resurfaced and are no longer candidates for these identities. This theory too, has several holes, relating to the times that the tomb was sealed. Edward IV died on 9 April 1483 and Lady Grey on 8 June 1492. Both were buried relatively quickly and the tomb resealed until 1789.
Suppose we test the theory that Richard III killed them and they are buried there, by assuming it. If so, one of these scenarios must have happened:
1) Edward Prince of Wales and Richard Duke of York both predeceased their father and were buried with him. Any source that gives either or both as alive after April 1483 is mistaken or worse.
2) Richard hid the bodies and someone else he trusted moved them into this tomb in 1492 – someone like Brackenbury, Catesby, Lincoln, Lovell, Norfolk or Ratcliffe, except that they were all dead and Brampton and Tyrrell were abroad. Lady Grey had to die some time and there would be such an opportunity.
3) Richard climbed out of his Greyfriars tomb one morning and bought a day return to Windsor after Lady Grey died, placed the coffins in the tomb himself (as (2)) during the days that it was opened for her funeral before catching the trains back to Leicester before his bedtime.
4) Richard didn’t die in 1485 but someone else was buried in his place. After smuggling the corpses into Edward’s tomb, as (2/3) above, he eventually really died and was substituted for the decoy corpse in Greyfriars – because he knew how important his mitochondrial DNA was to be five hundred years later. Nobody in the days after Bosworth had noticed that the wrong body was being exposed.
None of these are remotely plausible. The two small coffins probably relate to two of Edward’s unknown other children, by Lady Grey or a different mistress, or perhaps two of their young servants who died just before 1483 or 1492.
Back to square one for the denialists as their second theory is also a Swiss cheese.
