"Alberico de Ver" attested a charter of Conan II Duke of Brittany (who ruled in his own name from 1057 to 1066). One passage in the Complete Peerage highlights the absence of proof that this was the same person as Aubrey who later held lands in England. If it was the same person, his career would have been a long one from [1057/66] to [1112], which suggests that they may have been different persons.
William I King of England granted him estates, particularly in north Essex, south Suffolk and Cambridgeshire. He attested a royal charter as Chamberlain [camerarius] in 1084. [Domesday Book records “the land which belonged to Earl Aubrey”, including Compton, Durrington, Winterslow, in Wiltshire, Iffley and Minster in Oxfordshire. It is not certain that these entries apply to Aubrey de Vere who has not been identified with the comital title in other sources. In addition, the unusual heading to the section "the land which belonged to…" suggests that it may have been confiscated or relinquished before the date of Domesday.] Domesday Book records “Aubrey de Vere” holding numerous properties in Essex.
He acted as Sheriff of Berkshire in [1106]. The Chronicle of Abingdon records a donation by "dapiferi Albrici…et uxore eius Beatrice", with the consent of "eorum filiis…Albricus, Rogerus, Rotbertus, Wuillelmus".
“Godefridus de Ver, Albrici senioris filius, Albrici junioris frater” donated property to Colne priory by undated charter, which names “matre sua Beatrice”. 1
