I had to look up what happened to all the major characters excepting Henry VIII, Mary Tudor, and Catherine Howard (since we all know what happened to them) after Cromwell's execution in 1540.
Gregory Cromwell, Thomas's only son, did not get his father's last title of earl of essex, but still survived his father's downfall and was made Baron Cromwell. he became a wealthy landowner and died in in 1551.
Rafe Sadler unwisely helped Lady Jane Grey ascend to the throne for nine days after the death of Henry's son edward VI. he had to retire to the countryside after her arrest and the ascent of Mary Tudor, but he was restored to political good graces with the accession of Elizabeth I. He became involved in international intrigues involving her court, and died in 1580.
The Duke of Norfolk fell from Henry VIII's favor in 1546, and was imprisoned for high treason and stripped of his dukedom. After Henry's death in 1548, he was restored to favor by Mary I, whose accession he helped engineer. He died in 1554, his dukedom restored.
Stephen Gardiner fell out of favor starting with the marriage of Henry VIII to his last queen, Catherine Parr. Gardiner tried to get her arrested for heresy and failed; he was left out of the power structure of the court of Edward VI when Edward succeeded his father. However, he was retsored to power under Mary I, and even crowned her at her coronation. It still is a great question as to whether he was involved in the persecution of Protestants during her reign. He died in 1555.
Richard Rich participated in the prosecution of Bishop Gardiner under Edward VI and abetted the bad treatment of Mary I under her brother's reign. but Mary bore Rich no ill will, and he prospered under reign and under the early reign of her sister, Elizabeth I. He died in 1567, and his family was one of the wealthiest and most ennobled in all of England for the next three centuries.
No one seems to know what happened to Wolsey's illegitimate daughter Dorothy after the Dissolution of the Monasteries, when Cromwell awarded he1r a pension.
Thomas Wriothesley became the executor of Henry VIII's will, which made him Earl of Southampton. He was appointed part of the Regency council of Edward VI, Henry's son, but fell out of favor from it. he was making a political comeback when he died in 1550.
