The Roquefeuil Versols family appeared around 900 as an offshoot of the House of Barcelona, Spain, who were kings of Aragon. At this time they controlled vast territories in the Languedoc (southern France) under various noble titles. They lost their nobility and particule "de" with a natural filiation in 1752. There are no evidence or presomption that the name would as some would allege, been Germanized in "Rockefeller" or "Rockenfeld" (1644 - Claude de Roquefeuil disappeared in the German army). It comes from the possession of Roquefeuil.
The heiress Adelais de Roquefeuil married Bernard d'Anduze (1129). The Anduze was another powerful family which coined money. The son of Adelais and Bernard, Arnaud, "Contor de Nant" maintained the name of Roquefeuil. He, his brother Raymond and their descendants fought in the wars of the Middle Ages: the Cathar Crusade, Seventh Crusade and the Hundred Years War. From Arnaud were descended the Lords of Versols, in Aveyron, and of Saint-Étienne-de-Gourgas. Their best known member is Guillaume de Roquefeuil who signed the Treaty of Corbeil on behalf of King James I of Aragon in 1258.
That branch continued to be located in the Languedoc as landowners, and has mainly produced, since the French Revolution, doctors, lawyers, and a politician (Pierre-Frédéric Roquefeuil, conseiller général de l'Hérault, at the end of the Second Empire).
The related branch of the Roccafull served the King of Aragon and participated in the Reconquista of Spain from the Moors. Ramon Perellos y Roccaful was Grand Master of the Order of St. John from 1697 to 1720.
