More research news!

I spent half an hour in front of the Complete Peerage (couldn't work
it online) and found:
DE LA POLES: Edmund's widow d. Feb 1515. Their daughter was
Elizabeth, not Anne, and she probably died that year in an epidemic
at the nunnery. Lincoln's son was not mentioned. William was
imprisoned in 1502.
STAFFORDS: Thomas was beheaded, not executed in any other way. Mary's
marriage to William Howard took place just after her brother Baron
Edward died (he had been the Earl of Arundel's ward).

Does anyone else have any news?
