[2] His eldest brother, John, married the daughter of Hugh Courtenay, Earl of Devon, but died in 1350 in his father's lifetime.

[4] In 1360 Aubrey de Vere was made steward of the royal forest of Havering in Essex.

In 1388 his nephew, Robert de Vere, Duke of Ireland and 9th Earl of Oxford was deemed a traitor, causing Aubrey to lose his post of chamberlain.

However, after Robert's death in 1392, the king gave Aubrey the title of Earl of Oxford allowing him to take a seat in parliament.

An administrator of Aubrey de Veer appears as William Tasburgh, of Raylegh, parson, in 1401.
