Gruffudd Vychan

Sir Gruffudd Vychan (c. 1395 – 1447), also spelt in English sources as Griffith Vaughan, was a Welsh knight who supported the rebellion of Prince Owain Glyndŵr against the English, and captured the Lollard John Oldcastle, who was later immortalized by Shakespeare as John Falstaff. He was finally executed after the murder of Sir Christopher Talbot, son of John Talbot, 1st Earl of Shrewsbury.
