Prince Ernst August of Hanover’s youngest son and his bride-to-be reside in Madrid but chose London as the location for their civil ceremony as that is where his mother lives. The couple has been to a number of important family events over the years, including the 2015 nuptials of his stepbrother Pierre Casiraghi and Beatrice Borromeo. Earlier this year, the pair attended the annual Rose Ball in Monaco with the Prince’s stepsister, Charlotte Casiraghi and stepmother Caroline.
