I talk about Anne's trial in my post https://www.theanneboleynfiles.com/15th-may-1536-the-trial-of-anne-boleyn/5375/ but here is an excerpt with the information you need:-
The Letters and Paper, Foreign and Domestic, Henry VIII (LP x.876) tell us that the panel consisted of:-
“Charles duke of Suffolk, Hen. marquis of Exeter, Will. earl of Arundel, John earl of Oxford, Hen. earl of Northumberland, Ralph earl of Westmoreland, Edw. earl of Derby, Hen. earl of Worcester, Thos. earl of Rutland, Rob. earl of Sussex, Geo. earl of Huntingdon, John lord Audeley, Thos. lord La Ware, Hen. lord Mountague, Hen. lord Morley, Thos. lord Dacre, Geo. lord Cobham, Hen. lord Maltravers, Edw. lord Powes, Thos. lord Mount Egle, Edw. lord Clynton, Will. lord Sandes, Andrew lord Wyndesore, Thos. lord Wentworth, Thos. lord Burgh, and John lord Mordaunt.”3
but these names mean nothing until you examine some of them more closely:-
* Charles Brandon, Duke of Suffolk – Henry VIII’s brother-in-law and a man who, as I have already said, hated Anne Boleyn. He was also well aware of what his great friend the King wanted from this trial.
* The Marquis of Exeter and his cousin Lord Montague (Henry Pole) – Both men were supporter of the Lady Mary.
* Earl of Oxford – A good friend of the King.
* The Earl of Northumberland – Henry Percy who Weir describes as “now an ailing embittered man, whose former love for Anne had long since withered into contempt.”4
* Ralph Neville, the Earl of Westmoreland – A loyal servant to the King in the North.
* The Earl of Worcester – His sister, the Countess of Worcester, was said to have given evidence against the Queen and to have been they key witness.
* The Earls of Rutland and Huntingdon – Both of these men were related to the King and were royal favourites.
* The Earl of Sussex – One of the King’s best friends.
* Lord Morley – Father of Jane Boleyn, George’s wife, but a staunch conservative and a supporter of the Lady Mary.
* Lord Dacre – A man who had narrowly escaped from being convicted for treason and who obviously wanted to please the King.
* Lord Cobham – A man close to the King and possibly the husband of Nan Cobham, the woman mentioned as giving evidence against the Queen.
* Lord Grey of Powys and Lord Monteagle – Both were son-in-laws of the Duke of Suffolk.
* Lord Clinton – Husband of Elizabeth (Bessie) Blount and stepfather of the King’s illegitimate son, the Duke of Richmond.
* Lord Sandys – One of the King’s good friends and also Lord Chamberlain.
* Lord Windsor – Another friend of the King.
* Lord Wentworth – A relative of Jane Seymour. His aunt was Jane’s mother, Margaret Wentworth.
* Lord Mordaunt – A man described by Weir as “a career courtier who served on several treason trials”
Some (Alexander Aless, Chapuys, the Bishop of Faenza and Dr Ortiz) reported that Thomas Boleyn, the Earl of Wiltshire, was even present at his children’s trials but the Baga de Secretis makes no mention of his name. I do hope that he was not forced to sit in judgment on them.
Others present includes the Attorney General (Sir Christopher Hales), the Mayor of London (Sir John Aleyn), the French Ambassador and various foreign diplomats, and members of the public. Eustace Chapuys did not attend because he was ill.
