His origins are obscure and various regions have been proposed for his birthplace, from Zeeland to Brittany. He may have been
Norman, possibly from the region of
Ver in the Cotentin peninsula of western
Normandy, or
Ver-sur-Mer, but the evidence is such that no certainty is possible. Late medieval sources put forward claims of descent from
Charlemagne through the Counts of
Flanders or
Guînes. In fact, the only connection of the Veres of England with
Guînes in
Flanders was through a short-lived marriage; Aubrey I's grandson
Aubrey de Vere III married Beatrice, heiress to the county of
Guînes, in the 12th century, but there was no issue, and their marriage was annulled after six or seven years. In the
Domesday Book, he is listed as "Aubrey the chamberlain" and "Aubrey the queen's chamberlain" as well as Aubrey de Vere. He and his wife held land in nine counties in 1086. Both were accused of some unauthorized land seizures. 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. He served
King Henry I in the first decade of his reign as a chamberlain and local justiciar in the counties of Berkshire and Northamptonshire. 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. The youth appeared to have recovered but suffered a relapse, died, and was buried at the abbey. At the dying request of Geoffrey, Aubrey gave Abingdon Abbey his church of Kensington with its appurtenances of 2 hides and 1 yardland. His parents then founded a cell of Abingdon on land they donated for the purpose:
Colne Priory, Essex. Within a year of the formal dedication in March 1111, Aubrey I joined that community and died soon. His youngest son William died not long after his father. Both were buried at the priory, establishing it as the Vere family mausoleum.
Aubrey de Vere II then succeeded to his father's estates. Aubrey I was married by 1086. As his spouse's name is recorded as Beatrice in 1104 and Beatrice is named as the mother of his eldest son, she was almost certainly his wife in 1086. Beatrice attended the formal ceremony for the founding of
Earl's Colne Priory. Besides sons Geoffrey, Aubrey II, and William mentioned above, the couple's children included Roger and Robert. == Estates ==
