About Agnes of Essex

Agnes of Essex, Countess of Oxford was the daughter of a royal constable Henry of Essex and his first wife, Cecily. At the age of three she was betrothed to Geoffrey de Vere, brother of the first Earl of Oxford, and turned over to be raised by the Veres soon thereafter. She remained in the household of the earl of Oxford about three years, then moved to Geoffrey's care. In her eleventh year Agnes rejected the match with Geoffrey and by early 1163 was married to his eldest brother Aubrey de Vere III, 1st Earl of Oxford, as his third wife.
