Bourbon-Busset

The Bourbon-Busset family is a cadet branch of the House of Bourbon, being thus agnatic descendants of the Capetian dynasty. Historically, they have been regarded as non-dynastic since decisions rendered by King Louis XI. Possibly, however, the family may be canonically legitimate, in which case it is the most senior extant male-line branch of the Capetians, and senior to the Bourbons which reign today in Spain and Luxembourg and have in the past ruled France, Naples and Sicily, as well as to the House of Braganza, also Capetians by illegitimate descent. The head of the family uses the title of Count of Busset, which derives its name from the marriage of Pierre de Bourbon (son of Louis de Bourbon, Bishop of Liège) with Marguerite de Tourzel, heiress of the barony of Busset. Their son Philippe married Louise Borgia, Duchess of Valentinois, only legitimate child of Cesare Borgia, Duke of Valentinois.
