W E Wightman, *The Lacy Family in England and Normandy,
1066-1194*,
genealogical chart following p 260.
From same, p 175, 177-178: Eustace fitz John, Payn's eldest
brother, married Beatrice, the Vesci heiress, and thus
inherited through her the honours of Alnwick and Malton. Their
son assumed the surname Vesci, it being this William whose
sister probably married Henry I de Lacy of Pontefract. By his
second marriage Eustace had a son Robert. He in his turn
married Aubrey de Lisours, daughter of Aubrey the sister of
Ilbert II de Lacy, through whom the Pontefract honour descended
in 1194 to Roger de Lacy, grandson of Robert fitz Eustace.
Since the king's permission for the marriage of Robert de
Lisours with Aubrey de Lacy was only obtained in 1129-30, this
family link between the holder of the western Lacy lands and
the Pontefract family has little significance for the time of
Payn fitz John, save to demonstrate that at least two of the
sons of John 'Monoculus' were of sufficient standing to be
acceptable husbands for the daughters of major barons.
