Ranulf de Gernon, 4th Earl of Chester was the son of the magnate who originated in what city in Normandy?
Ranulf de Gernon, 4th Earl of Chester Ranulf II (also known as Ranulf de Gernon) (1099–1153) was an Anglo-Norman potentate who inherited the honour of the palatine county of Chester upon the death of his father Ranulf le Meschin, 3rd Earl of Chester. He was descended from the Counts of Bessin in Normandy.
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).
