That's good enough for me.  So: 

 : The last male Capetian not descended from Louis XIII was Louis Henri, Prince of Condé (died 1830), descended from the youngest son of Charles, Duke of Vendôme. 
 : The last male Capetian not descended from Charles, Duke of Vendôme, was Roger de Chevillon (died 1733), descended from Peter I of Courtenay, youngest son of Louis VI of France. 
 : The last male Capetian not descended from Louis VI was Ferdinand I of Portugal (died 1383), descended from the younger son of Robert II of France. 

 I do like brevity! —
