Hi - I am researching and writing a biography of Queen Katherine Howard and I have just finished reading Elisabeth Wheeler's study of her. Not only does Wheeler suggest that the execution was carried out secretly at night-time, but she argues that Katherine was never buried in the Chapel of St Peter ad Vincula, near Anne Boleyn - as her body was never found in the Victorian period. She suggests Katherine may have been buried elsewhere.
I have also read Weir's "Lady in the Tower" and she suggests that the body identified as Anne Boleyn may actually be Katherine, which I disagree with.
I personally believe that Katherine WAS buried in this chapel, and like Lady Jane Grey, her bones were never discovered as they had dissolved due to her age (both were teenagers).
Can anyone provide me with further info / their own ideas? Thanks.
