The work of Anthony M. H. J. Stokvis establishes the genealogy of the Albrets to start with the 800s AD Basque nobleman Jimeno of Pamplona, patriarch of the Spanish Jiménez dynasty.
At that time the House of Albret had attained considerable territorial importance, due in great part to the liberal grants which it had obtained from successive kings of France.
Their son Henry II, King of Navarre, was created Duke of Albret and a peer of France in 1550.
By his wife Marguerite d'Angoulême, sister of Francis I, Henry II had a daughter, Jeanne d'Albret, Queen of Navarre, who married Anthony de Bourbon, Duke of Vendôme, and became the mother of Henry IV, King of France.
[6] The title of Duke of Albret was later granted to the family of La Tour d'Auvergne (see duc de Bouillon) in 1651, in exchange for Sedan and Raucourt.
[7] A cadet of this house was Jean d'Albret-Orval [fr], seigneur of Orval, count of Dreux and of Rethel, governor of Champagne (died 1524), who was employed by Francis I in many diplomatic negotiations, more particularly in his intrigues to get himself elected emperor in 1519.
