[4] By this time, the Angevins, Fulk II included, had become particularly adept at establishing marriage alliances that furthered their goals.
[5] His father, Fulk the Red, had arranged his marriage to Gerberga, daughter[6] of Geoffrey of Nevers and Aba.
[b] Among other things, this alliance enabled Fulk to open the doors towards Aquitaine for his daughter, Adelaide-Blanche, to marry a future king of France (Aba was likely[7] a daughter of William I, Duke of Aquitaine, and Engelberga, thus of royal blood) and for his son Guy to become Bishop of le Puy.
[8] After Gerberga's death c. 952, Fulk made another astute political marriage to the widow of Alan II, Duke of Brittany.
[8] He is said to have ordered the murder of Drogo, Duke of Brittany, Alan II's son with the latter, according to the Chronique de Nantes.
