Children. 661 John and Margaret has 2 other children whose names were not recorded in the Mistress of the Monarchy book.

Unique in English history - Legitimized in law, 1397. 707 King Richard II issued Letters Patent formally legitimizing the Beaufort children in law and then secured an Act of Parliament. Being formally declared legitimate facilitated the full acceptance of the Beauforts into the royal house, removed all barriers to their preferment in the peerage and the Church and further improved their prospects. However, the wits of Richard II's court derisively referred to the Beauforts as "Fairborn", an interpretation that was still being used ironically a century later, proof that the taint of bastardy still clung to the family.

This Act is unique in English History

Prosecution, 1397. 715 Thomas, the Duke of Gloucester, and uncle to King Richard II, was accused by the King of conspiring with the Earls of Arundel and Warwick to depose and imprison the King. Thomas (Gloucester) was arrested and almost certainly murdered by orders of the King. Gloucester was not present on September 21 when the three appellants were called upon to answer for their treason.

John Beaufort assisted in the prosecution of his uncle Gloucester (John of Gaunt's brother). John was created Duke of Somerset and Dorset by King Richard at about this time. On November 20, John was appointed Constable of Wallingford Castle for life by the King.

King's Lieutenant, Aug 1398. 716 John was appointed the King's Lieutenant in Aquitaine by King Richard II for seven years. His father, John of Gaunt, had relinquished the Duchy of Aquitaine that year perhaps in recognition that he could no longer bear the responsibilities of that turbulent domain. John of Gaunt died in early 1399.

Relegated to Earl, 1399. 657 John had publicly supported King Richard when Henry, Duke of Lancaster, was trying to overthrow him. After Henry became King, John was deprived of the marquessate of Somerset and relegated to the rank of earl. However, Henry soon made him his chamberlain and admitted him the the royal council.

Career, until 1404 or 1405. 713 John was Captain of Calais until this date. He was in Calais when his mother passed away.

John married Lady Margaret Holland Duchess of Clarence, daughter of Sir Thomas de Holland K. G. , Second Earl Kent, Third Earl of Holland and Lady Alice Fitzalan of Arundel. (Lady Margaret Holland Duchess of Clarence was born in 1385,540,717 died on 31 Dec 1439 in St. Saviour's Abbey, Bermondsey, London, England 540,661,717 and was buried in Canterbury Cathedral, England 540,717.)
