Legitimation of the Beauforts

Calendars. 28. Be it remembered that on Tuesday, the fifteenth day of the parliament [4 February 1397], the chancellor (age 53), by order of the king (age 30), declared that our holy father the pope, in reverence of the most excellent person of the king (age 30) and his honourable uncle the [his father] duke of Guyenne and of Lancaster (age 56), and of his blood, has enabled and legitimized my lord [his illegitimate brother] John Beaufort (age 24), his brothers [Note. [his illegitimate brother] Cardinal Henry Beaufort (age 22) and Thomas Beaufort 1st Duke Exeter (age 20)], and his [his illegitimate sister] sister (age 18). And therefore our lord the king, as sole ruler of his kingdom of England, for the honour of his blood, willed and enabled of his abundant royal power, and legitimized, of his own authority, the said John, his said brothers, and sister. And he also pronounced and published the ability and legitimation, according to the form of the charter of the king made thereon.

Calendars. 29. Which charter was read in full parliament, and delivered to the said [his father] duke, father of the said John, and his said brothers and sister; the tenor of which charter follows:

Richard, by the grace of God, king of England and France and lord of Ireland, to our most beloved kinsmen the noble [his illegitimate brother] John, knight, [his illegitimate brother] Henry, cleric, Thomas, donzel, and our beloved noblewoman [his illegitimate sister] Joan Beaufort, lady-in-waiting, our most beloved cousins born of our uncle that noble man John duke of Lancaster, our lieges, greeting and the goodwill of our royal majesty. While inwardly considering how endlessly and with how many honours of parental and sincere affection of our aforementioned uncle and of his mature counsel we are on all sides blessed, we have judged it appropriate and worthy that in consideration of his merits, and in contemplation of the grace of persons, we should endow you, who are resplendent with probity and virtuous life and conduct, and are born of royal stock and divinely marked with many virtues and gifts, with the protection of grace and favour by special prerogative. Thus it is that, yielding to the prayers of our said uncle, your father, we grant to you who, so it is claimed, have suffered such defect of birth, that, notwithstanding this defect, which, together with its various consequences, we wish to be fully included in these presents, you may nevertheless receive all honours, dignities, preferments, estates, degrees, and public and private offices, both perpetual and temporal, and feudal and noble rights, by whatsoever name they are called, such as duchies, lordships, earldoms, baronies, or whatsoever other fiefs they be, whether they be dependent upon or held of us mediately or intermediately, which may be preferred, promoted, elected, taken up and allowed, and received, retained, performed and exercised prudently, freely and lawfully, as if you were born in wedlock, notwithstanding any statutes or customs of our kingdom of England decreed or observed to the contrary; and we dispense you [from this defect] by the tenor of these presents, by the plenitude of our royal power and with the assent of our parliament; and we restore you and each of you to legitimacy.

Excerpta Historica Page 152. [1433.] Nothing more has been discovered of Sir Thomas Swynford (age 66), excepting that the Duke of Exeter, his half-brother, bequeathed him, by the appellation of "my brother," a silver-gilt cup, and that he died in the 11 Hen. VI. 1432-31, having alienated his lands in Lincolnshire, as the inquisition on his death finds that he held nothing in that county. He appears to have had issue two sons, Thomas (age 27) and William (age 25). Of William, all that is known is, that his half-uncle, [his illegitimate brother] Cardinal Beaufort (age 58), by a codicil to his will, dated in 1447, in which he called him "William Swynford my nephew," left him 400l. with a certain quantity of silver vessels.
