Gilbert (Crispin) De Brienne Count of Brienne

  General Notes:

Gislebert, Count de Brionne, nephew of Richard duke of Normandy (ref to Richard II),
gave his niece in marriage to Baldric the German, who
came into Normandy, with Viger his brother, to take service
under the duke (presumably Richard II). From this marriage sprung six sons,
besides several daughters, viz. : Nicholas de Basqueville ;
Fulk d'Aunoun ; Robert de Courcy ; Richard de Neuville,
Baldric de Bauquencey; and Viger of Apulia. They all distinguished
themselves by great valour under Duke William,
from whom they received great riches and honours, and left
to their heirs vast possessions in Normandy.
