Odd - the facsimile version of the register I used (in the British Library) said there were 31 ballads. I misnumbered 2 (call them 15a and 24a) which makes 33. Presumably the 31 in the register ignored the two pairs of ballads in the list, whereas I just cocked up with the numbering.

BTW, I looked up the background of the two "death" ballads. Edward VI died of Tuberculosis (consumption) on 6th July 1553, aged 15. Edward Stafford, 3rd Duke of Buckingham, was executed for treason by Henry VIII in 1521 (apparently he got in the way of Wolsey's ambitions).
