[2] The first notice of Aubrey de Vere is as a young boy witnessing his father's charters for Colne Priory.

[1] In 1195 he was assessed to pay 500 marks towards the ransom of King Richard, who was being held captive by the Emperor Henry VI.

[5] The title had already been confirmed to his father by Matilda's son, King Henry II and Aubrey III had been acknowledged earl of Oxford by Richard I and John.

[7] In what may have been his last military service, the earl of Oxford was with King John's forces during a nine-week campaign in Ireland from June to August 1210.

[3] He was succeeded by his younger brother, Robert de Vere, 3rd Earl of Oxford, later one of the guarantors of Magna Carta.

The earl left an illegitimate son, Roger de Vere, who was apparently acknowledged and provided for by his father.
