David Tudor

David Tudor (1459-1535) was the illegitimate son of Owen Tudor, the second husband of the Dowager Queen Katherine of Valois. David Tudor changed his name, or rather adopted the more Welsh version of his name, and so became David Owen.

David was therefore a close blood relative of the Tudor kings Henry VII, whom he fought for at the Battle of Bosworth in 1485, and Henry VIII and due to this was able to marry well and hold positions at the royal court. He was a Knight of the Body under Henry VII and the King's carver during the years 1486-1529, he was also brought to give testimony during the divorce proceedings of Henry VIII and Katherine of Aragon. Away from court positions, David was the Constable of Winchester and Sheriff of Hampshire. David was also one of the chief mourners at the funeral of his nephew King Henry VII in 1509 due to his blood affinity to the monarch.
David Owen was the only member of the Tudor bloodline to only have Tudor blood, and not the royal Valois blood that his half-siblings had. However, despite this it appears that he was not sidelined and enjoyed a long and successful life and was an active member of the Tudor family, being close in particular to his nephew Henry VII.
David Owen's will was proved seven years after his death in 1542 and included that he willed "an obit be kept yearly, the morrow for the souls of King Henry the Seventh, Edmund sometime Earl of Richmond, Jasper Duke of Bedford, my father, my mother". He also requested to be buried alongside his first wife Mary Bohun. In his will he left 500 marks to his two daughters by his third wife Anne, 300 marks to his illegitimate daughter Barbara, and a silver cup to his daughter Anne (Hopton). His estates were left for the use of his wife Anne for the remainder of her life and then in succession to his son Owen, his son John, his son Jasper and his grandson David (son of Henry Owen).
