The most titled person in the world is the 18th Duchess of Alba, Doa Mar¡a del Rosario Cayetana Fitz-James Stuart y Silva (b. 28 Mar 1926). She is 14 times a Spanish grandee, 5 times a duchess, once a countess-duchess, 18 times a marchioness, 18 times a countess and once a viscountess.

This is due to the complicated combinations of nationalities and marriages intertwined within her ancestry.
