[2] Aubrey's estates were valued at approximately £300, putting him in roughly the middle ranks of the post-conquest barons of England in terms of landed wealth.
[4] Sometime in or before 1104, Aubrey's eldest son Geoffrey fell ill and was tended at Abingdon Abbey in Berkshire by the royal physician, Abbot Faritius.
At the dying request of Geoffrey, Aubrey gave Abingdon Abbey his church of Kensington with its appurtenances of 2 hides and 1 yardland.
[8] The principal estates held by Aubrey de Vere in 1086: Castle Hedingham, Beauchamp [Walter], Great Bentley, Great Canfield, Earls Colne, [White] Colne, and Dovercourt, Essex; Aldham, Belstead, Lavenham, and Waldingfield, Suffolk; Castle Camps, Hildersham, Silverley, and Wilbraham, Cambridgeshire.
Of the barony of Count Alan of Brittany, he held the manors of Beauchamp Roding, Canfield, and West Wickham, Essex.
Aubrey's seizures or questionable right of possession to estates included Manuden, Essex; Great Hemingford, Huntingdonshire; and Swaffham, Cambridgeshire.
