"Thomas Beaufort, 1st Duke of Exeter, KG (c. 1377 – c. 31 December 1426) was an English military commander during the Hundred Years' War, and briefly Chancellor of England. He was the third of four children; the son of John of Gaunt, Duke of Lancaster, and his mistress Katherine Swynford. To overcome their problematic parentage, his parents were married in 1396, and he and his siblings were legitimated on two separate occasions, in 1390 and again in 1397. He married the daughter of Sir Thomas Neville of Horneby, Margaret Neville, who bore him one son, Henry Beaufort. However, the child died young."
