line of French kings (who also ruled in Naples and Spain), of whom it was proverbially said, "they learn nothing and forget nothing." The royal family ruled in France 1589-1792 and 1815-1848; its name is from Bourbon l'Archambault, chief town of a lordship in central France, probably from Borvo, name of a local Celtic deity associated with thermal springs, whose name probably is related to Celtic borvo "foam, froth."
