In page Elizabeth Seymour, Lady Cromwell:

"

This undated letter is placed at the end of July 1540 in Letters and Papers of the Reign of Henry VIII.[37]It was probably written while Thomas Cromwell was imprisoned in the Tower, as Elizabeth refers to her father-in-law, and not her late father-in-law. Moreover, it was customary at that time to write "may his soul God pardon" or something similar when referring to someone who had recently died, which she did not do.[38] The letter was almost certainly written on the advice of her brother, Edward.
