Richard sent Elizabeth away from court to Sheriff Hutton and publicly rebutted these rumours on 30 March 1485 during an assembly of Lords he summoned at the Hospital of St. John. Addressing them "in a loud and distinct voice", he "showed his grief and displeasure aforesaid and said it never came into his thought or mind to marry in such manner wise, nor willing nor glad of the death of his queen but as sorry and in heart as heavy as man might be …". There is no reason to doubt that Richard's grief over his wife's death was genuine. Documents later found in the Portuguese royal archives show that after Anne's death, Richard's ambassadors were sent on a formal errand to negotiate a double marriage between Richard and the Portuguese king's sister Joanna, of Lancastrian descent, and Elizabeth of York and Joana's cousin Duke Manuel (the future Manuel I).
