The Angevins, Fulk II included, had become very good at making marriage alliances that helped their goals. His father, Fulk the Red, had arranged his marriage to a Carolingian, Gerberga, the daughter of Ratburnus I Viscount of Vienne. Among other things this marriage made it possible for their daughter Adelaide-Blanche to marry a future king of France. It made them important enough for their son Guy to become Bishop of le Puy.
