John of Gaunt, King Edward III’s fourth…
1396 CE
John of Gaunt, King Edward III’s fourth son and Duke of Lancaster, in 1396 marries his longtime mistress Katherine Swynford (who is also the sister of Geoffrey Chaucer’s wife, Philippa de Roet).
The crown, in the person of Gaunt’s nephew Richard II, legitimizes his children by her (as the Beauforts) but bars them from succession to the throne.
In this year also, John’s daughter Joan weds Ralph de Neville, who in 1388 had become the fifth Baron Neville de Raby.
