Fulk was the son of
Geoffrey I of Anjou, also known as Geoffrey
Grisegonelle, and
Adele of Meaux, daughter of
Robert of Vermandois, Count of Meaux and Troyes, and Adelaide of Burgundy. He had an older sister,
Ermengarde-Gerberga of Anjou, who married
Conan of Brittany, and a younger brother, Geoffrey. A half-brother, Maurice, was born in 980. Fulk married Elisabeth of Vendôme (c. 979–999), daughter of Count Bouchard of Vendôme, and they had one daughter, Adèle, who married Bodon, son of Landry,
Count of Nevers. Their eldest son, Bouchard, inherited Vendôme. There are varied stories regarding Elisabeth's death. One story was recounted in the
Chronicles of Saint-Florent: Elisabeth occupied the citadel at Angers with some supporters and while under siege from Fulk, she fell from a great height, and then was burnt at the stake for
adultery. Another story is that Nerra trumped up these charges of adultery, seeking to be rid of Elisabeth, because she had not given him a son. By age 20, she had only given birth to a daughter, and appeared to be sterile, as no other pregnancies occurred in the continuing years of their marriage. According to the account given in ''La Chronique de Saint Aubin d'Angers'', cited in Ina Caro's book,
The Road from the Past, he "had her tried at an ecclesiastical court in Angers, by judges he knew would convict her; then he had her dressed in her gaiest clothes and personally led her out to be burned at the stake in the square in front of the cathedral." Fulk subsequently married Hildegarde of
Sundgau, whose family was from
Lorraine, around December 1005. They had two children: •
Geoffrey II, in 1006, who became known as Geoffrey Martel and succeeded Fulk as
Count of Anjou in 1040. •
Ermengarde-Blanche, born sometime in 1017. == Combat ==
