The de Forcade family, sometimes written Forcade (de la), Fourcade (de) and Fourcade (de la), belongs to the nobility of Guyenne.^[1]

The house of de Forcade and de la Forcade, from the town of Orthez, in Béarn, is one of the oldest families of the province, with one of its members in the 12th century, figuring among those Lords of Béarn possessing fiefs and giving tithes to the church in Orthez. It always held rank at the Order of Nobility of the States of Béarn, as evidenced in a judgment by the Court of Aids of Guyenne. They served as the Counts of Foix and Béarn during the English Wars; participated during the 14th, 15th and 16th centuries, in the oversight of proofs and reviews of nobility; and later continued into the 19th century providing France with governors of jurisdictions and distinguished military officers, many of whom were killed on the battlefield in the service of their country.

The family's nobility was reconfirmed through numerous judgments by the stewards responsible for the royal administration of Béarn ("les intendents"), by judgments of the Court of Aids (the Court of Appeals) of Guyenne and the Conseil d'Etat (France).

The Seigneur de Forcade, Seigneur de Baylens and Seigneur de Cando were three Béarnais Lords, who, circa 1170, gave the tithes of the parish of Castetarbe, in Orthez, to Guillaume-Bertrand, Bishop of Dax, son of Bertrand, Viscount de Labour and brother of Viscounts Pierre and Arnaud.
