Her famous in-laws
Santo Domingo, you say? Why yes, that does make Charlotte the sister-in-law of our own NYC queen of the scene, Lauren Santo Domingo, who is married to Alejandro's brother, Andres. On her hubby's side, she's also linked to the royal family of Monaco (her husband's niece, Tatiana, is the wife of Andrea Casiraghi, son of Princess Caroline). Charlotte's own cousin, Sofia Wellesley, is, randomly enough, married to singer James Blunt.
