Geoffrey V (Geoffroy V) (died 1218), Viscount of Châteaudun, son of Hugh VI, Viscount of Châteaudun, and Jeanne de Preuilly, daughter of Gosbert de Preuilly, Seigneur of Bouchet and Guerche, and Adela de Vendôme.
In 1213, he granted the nuns of Rives the right to graze their livestock in the forest of Epinat.
[1] Geoffrey’s first marriage was to Adelicia de Nevers.
Adelicia is listed in Europäische Stammtafeln as Geoffrey’s wife but no heritage is identified.
The most likely candidate for her parents are William IV, Count of Nevers, and Eléonore, Countess of Vermandois, although this has not been verified.
