Theodore Nott, Marquess of Felixstowe (b. 3 June, 1980) was a Pure-blood wizard and the son of Androginious and Ariadne Nott.
Descended from a long line of pure-blood wizards going back to the 600ADs, Theodore was born to Androginious and Ariadne Nott, the Duke and Duchess of Midlothian, on 3 June, 1980 in Nott Castle, situated in the heart of Suffolk. As the eldest son and heir to the couple, he automatically obtained the title of Marquess of Felixstowe, the subsidiary title of his father, on the moment he was born.
