• She was the dau. of Sir Payn Roet, a Gascon, and the widow of Sir Hugh Swynford.
2853• Katherine, who apparently had had plague, was sent to a convent at Sheppey to be raised and educated. At the age of 16, she went to court and married, seemingly against her will, Hugh Swynford, with whom she had two children.
After Hugh’s death, she became John’s mistress and as such was appointed guardian of his daughters. She travelled around John’s various castles but was mainly based at Kenilworth. She spent time at Bolingbrook and at the Savoy and was seemingly treated as John’s consort in preference to his wife Castanza.
2859, p 5• All her issue [by John, Duke of Lancaster] legitimated by charter of Richard II, 1397.
2834,2883, p 12• [excerpts John and Katherine between them started the Tudor and Yorkist Royal Houses directly and most of the European Royal Houses can trace their origins back to them through intermarriage. This was not bad for a Flemish Heralds daughter! They had fulfilled Merlin’s ancient prophecy “thou shalt get kings though there be none!”
She was John’s third wife and was Duchess of Lancaster for three years from January 1396 to February 1399 when John died at Leicester Castle. Following the death of Richard the II’s first wife, Anne of Bohemia, and until his marriage to Isabel of France, whe was the first lady of England and granted wardship of Isabel.
2859, p 1• Thus, the daughter of a Flemish Herald became the first lady of England, co-founder of most European Royal Houses and a powerful, if invisible, influence on history.
2859, p 5• Her son Henry was Bishop of Lincoln at the time [of her death], and she was buried by the high altar in the cathedral. Her daughter Joan was also buried there and her tomb can be found if you are facing to the right of the altar. All the decoration and brasses of them have gone, so even her grave gives no idea of her importance to history.
2859, p 2
• Bearing this in mind, it seems odd that, in the teeth of opposition, scandal and her non-royal status, he [John] should then eventually marry her, have their four children declared legitimised and elevate her to Queen of the realm in all but name. This was after about 10 years apart, with no contact during which time he had had quite a few lady friends, a wife and several more bastards.
2859, p 2• It is known that John and Katherine disappeared for several weeks prior to his second marriage [1370], and presumably this is when she became his mistress. She returned to England and was obviously pregnant because she gave birth to John, later John Beaufort. It was assumed that John was Hugh’s posthumous child, but when Henry was born to John and Katherine, they acknowledge John as theirs.
