Estrildis

Estrildis was the legendary daughter of the king of Germany according to Geoffrey of Monmouth. She was found in the ships of Humber the Hun after his defeat by Locrinus, son of Brutus. She was said to be the most beautiful woman of her time and Locrinus sought to marry her. Unfortunately, Gwendolen, the daughter of Corineus of Cornwall, was betrothed to Locrinus and he had to submit. He created a cave for Estrildis beneith Trinovantum (London) for her to live under the care of servants. She was visited by Locrinus for seven years in secret, trusting no one but the servants and a select few. At last, she gave birth to a daughter whom she named Habren. When Corineus finally died, Locrinus deserted Gwendolen and named Estrildis queen. A battle was fought between Locrinus and Gwendolen, and Locrinus was killed. Estrildis and Habren, as a result, were thrown into a river which was thereafter called "Habren" (Afon Hafren) in Welsh, which is the River Severn in English.
