Gruffudd Vychan

Sir Gruffudd Vychan ( 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.

Family Lord of Burgedin, Treflydan, Garth and Gearfawr, Vychan was the second son of Gruffudd ap Ieuan ap Madoc ap Wenwys by Maud, daughter of Griffri ap Rhys Fongam.

The Welsh poets were infuriated by Grey's treachery, and the indignant elegies of Lewis Glyn Cothi and Dafydd Llwyd ap Llywelyn ap Gruffudd (Dafydd Llwyd o Fathafarn) have survived. In the second of these, Dafydd Llwyd o Fathafarn expresses the deep sense of anger and loss in Powys at the taking of his life:

Descendants Gruffudd was succeeded by his children David Lloyd (who inherited Garth), Cadwaladr, Reinallt (Reginald) Vychan, Gwenhwyvar, Catherine, Anne, and Margaret. Reinallt and David Lloyd received the royal pardon on 21 December 1448.

On David Lloyd's death in 1497, his wide estates were divided between the children of his two marriages, who founded numerous families of Montgomeryshire Lloyds. David Lloyd's son, Humphr(e)y Lloyd, became the first High Sheriff of Montgomeryshire in 1541.

Reinallt, or Reginald, was the ancestor of the Wynnes and Myttons of Garth and the Derwes family.
