and a second question - should the profile's LNAB be changed from Ghent to Unknown?
The Wikipedia article for her husband gives only "Beatrice"
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.[7]
The article also mentions that she "held Aldham, Essex, in her own right of Odo bishop of Bayeux."
There is a roundabout connection to the Count of Manassès, in that her husband's Wikipedia article states that "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." The linked article about Guînes includes the statement that, at the beginning of the 11th century, "Count Manassès founded a convent of the order of Saint-Benoit."
The profile currently attached as Beatrice's mother is Sibilla (Manasses) Ghent (abt.1005-). That profile also carries the warning: "Research suggests that this person may never have existed." It also has no sources and is not connected to any parents.
