“… My lord of Suffolk hath lately sent to me to bear with him part of the charges, as well of my son Marquis being in the court, as of my lady his wife being in the country; or else she and her train to be with us. [...] When my lord of Suffolk made suit to the King for the marriage of my son, it pleased him to refer therein to my “condyscente” in that behalf. I wrote to my lord of Suffolk that since it was his pleasure to match my son into honorable blood, if he would see me discharged of my bond for support of my son during his minority, I would consent. […] Though my lord of Suffolk bears these charges, according to his promise, for three or four years, yet when he comes of age the charge of him, his wife and all their train will fall upon me, and then they will be much greater.” British-History
