I recommend myself to your royal and high lordship in the most obedient manner which, with my whole, entire, and simple heart, I can most humbly do, as she who desires to know of you, and of your most noble estate and most perfect health, such prosperity as your royal and most honourable heart can desire. And may it please your high nobleness to understand that I write now to your royal presence in behalf of your loyal liege and esquire, Christopher Standith, who, as he has certified me, has been in your service in Wales every time you have been there against your enemies, and besides, in all your most honourable journeys since your coronation, in which he has expended the substance that he could acquire of his own and of his friends, in such wise that, whereas he and my well beloved his wife Margaret (daughter to Mr. Thomas Fleming, who was chancellor and servant during his life to my most honoured and redoubted lord your father, whom God assoil) kept house and establishment, they have left it, and the said Margaret is lodged very uncomfortably with her children, of whom she has many, having one or two every year; and all this on account of the great charge which her said husband has incurred and still incurs in your service; to whom, of your gracious goodness and gentleness, you have aforetime promised guerdon of his labour, whenever he should spy out [something] from which [he could have a living] of 40 marks or of 40 pounds. And, most puissant and excellent prince and my most sovereign lord, he is the youngest [and his father has dismissed him from] his service, and that merely because he and his wife married each other for downright love, without thinking this time [what they should have to live upon. Wherefore 1) entreat your most high and puissant lordship to consider that the said Margaret should dwell [in some suitable place, or else with the queen your wife, whom God protect; and that she is come to me trusting that my [intercession] might avail her with you. May it please you to be gracious lord to her and her said husband, and of your guerdon [assist them] to support in their persons poor gentility, that their affiance may turn to good effect for them, and to my honour, if it please you, by their finding succour from your royal and most excellent nobility^ on account of this my most effectual supplication.
Most high and puissant prince and most excellent sovereign lord, I pray God to grant you a most honourable and long life, and preserve you in his most excellent keeping, and give entire joy and gladness as much as your gentle and most noble heart would choose or desire.!Written at the castle of Raby [Map]. Your most humble and obedient subject, if it please you, J. DB W.

Letters Patent Of King Henry The Fourth Certifying The Legitimacy Of Sir Thomas Swynford; With Notices Of The Swynford Family.
Every one is aware that John of Gaunt, "time-honoured Lancaster," formed an illicit connection with Katherine, the widow of Sir Hugh Swynford, and daughter and coheiress of Sir Payne Roet, Knight, a native of Hainault, and Guienne King of Arms, and that he subsequently married her.
This lady had been governess of the Duke's daughters by his first wife, when his attachment to her, perhaps, commenced. In March 1377, Lady Swynford obtained a confirmation from Edward the Third of a grant from the Duke of Lancaster, of the manors of Gryngelley and Wheteley for life.1 On the 27th December, 3 Ric. II. 1379, the Duke granted her the wardship of the heir of Bertram de Sanneby, "pour le bone et greable service quelle nostre treschier et bien amee Dame Katherine Swynford, Maistresse de noz tresames filles Philipe et Elizabeth de Lancastre, ad fait a nos dittes filles;" and in September, 5 Ric. II. 1381, he gave her an annuity of two hundred marks, payable out of his honor of Tickhill.2 The Duke's second wife Constance, daughter and heiress of Peter, King of Castile and Leon, died in 1394; and two years afterwards, namely, on the 13th January 1396, being then about the age of fifty-four, he married Lady Swynford at Lincoln, to the great displeasure of the Duchess of Gloucester and other ladies of the blood royal.3 As Lady Swynford was then upwards of forty, and had been the Duke's mistress above twenty years, it may be inferred, that gratitude and conscientious motives were his only inducements for making her his wife. The Duke of Lancaster had by her, before his marriage, four children, who were surnamed Beaufort, from being born in Beaufort Castle in France: namely, John, who became Earl and Marquess of Somerset; Henry, Bishop of Winchester and Cardinal of England; Thomas, Duke of Exeter;4 and Joan, who married Ralph Neville, Earl of Westmoreland. All these children obtained letters of legitimation from Richard the Second, in February 1397, which was preceded by a similar act by the Pope. The King's patent for the purpose was read in the Parliament then sitting at Westminster;5 and the proceeding was ratified and confirmed by its authority. On the same occasion, Sir John Beaufort was created Earl of Somerset to hold to him and the heirs male of his body.6
