Lady Salisbury Forgotten Prisoner in the Tower of London

de bene esse: literally, of well-being, morally acceptable but subject to future validation or exception

Of all the prisoners that are not usually mentioned I think Lady Salisbury was the most unjustly imprisoned and executed. A cousin to Queen Catherine's father, Sir Thomas Parr, Margaret was the only surviving daughter of George, Duke of Clarence (brother of Edward IV and Richard III) and Lady Isabel Neville (daughter of Lord and Lady Warwick and sister of Queen Anne).

Of those less known listed within the blog -- who do you think was the most unjustly imprisoned and/or executed (this list does not include the two wives of Henry VIII or Elizabeth Tudor)? And why?
