The daughter of Sir Payne (or Paen/Pain/Paon) (de) Roet (also spelled (de) Rouet, (de) Roët or (de) Roelt), originally a Flemish herald from County of Hainaut, later knighted.
Katherine became the third wife of John of Gaunt, Duke of Lancaster, and their descendants were the Beaufort family, which played a major role in the Wars of the Roses. Henry VII, who became King of England in 1485, derived his claim to the throne from his mother Lady Margaret Beaufort, who was a great-granddaughter of Gaunt and Katherine Swynford.
The Dukes of Beaufort continue in the male line today.
