Relationships
Father: Gulbert.
This relationship is (tentatively) given by Fowler. It is recorded by Ordericus Vitalis (3:41-42).
Mother: uncertain.
It seems that she was a daughter of Richard, the duke of Normandy, but sources differ as to which Richard -- I, II, or III. (III would seem to be chronologically impossible.) Her name was possibly Papia, but this, too, is not entirely clear.
Spouse: unknown.
Children:
Walter de St Valéry married Elisabeth, sister of Miles de Montlhery.
