Cawley cites the Rotuli de Dominabus of 1185, which says that in 1185 Alda had four daughters, of which the eldest was 16 years old and in the custody of Hugh de Beauchamp.
"Alda que est filia Hugonis de Bello-campo, et fuit uxor Willelmi Maubanc, est de donatione Domini Regis, et est xxx annorum; et habet iiij filias, quarum primogenita est xvj annorum, et in custodia Hugonis de Bello-campo."
