Wellesley is the daughter of the Duke of Wellington and Princess Antonia of Prussia, who is a relative of Queen Elizabeth II and Prince Philip.

But the grooms side of the family also has some royal connections: Alejandro's niece, Tatiana Santo Domingo attended the wedding with husband Andrea Casiraghi, son of Caroline, Princess of Hanover and nephew of Prince Albert II of Monaco. If that wasn't impressive enough, Tatiana's father (the grooms brother) is married to Moda Operandi founder Lauren Santo Domingo, who also attended.
