Ranulf de Gernon, 4th Earl of Chester was the son of the magnate who originated in what city in Normandy?
Ranulf le Meschin, 3rd Earl of Chester Ranulf le Meschin, 3rd Earl of Chester (1070−1129) was a late 11th- and early 12th-century Norman magnate based in northern and central England. Originating in Bessin in Normandy, Ranulf made his career in England thanks to his kinship with Hugh d'Avranches - the earl of Chester, the patronage of kings William II Rufus and Henry I Beauclerc, and his marriage to Lucy, heiress of the Bolingbroke-Spalding estates in Lincolnshire.
Ranulf I of Aquitaine Ranulf I (also "Ramnulf", "Rannulf", and "Ranulph") (820–866) was a Count of Poitiers (from 835) and Duke of Aquitaine (from 852). He is considered a possible son of Gerard, Count of Auvergne, and Hildegard (or Matilda) "[more likely Rotrude, see Gerard, Count of Auvergne and Louis the Pious]", daughter of Louis the Pious and Ermengard. Few details are known about Ranulf I, except that he died in 866 in Aquitaine from wounds received in the Battle of Brissarthe against the Vikings (in which Robert the Strong also died).
