According to NewsBinding:
The Duke of Noto married Lady Charlotte at The Cathedral of Monreale, nearby the town of Palermo…
Charlotte, 28, is the youngest daughter of Scottish businessman James Lindesay-Bethune, 16th Earl of Lindsay, and Diana Mary Chamberlayne-Macdonald. The Duke, 29, is the heir apparent to Prince Pedro of Bourbon-Two-Sicilies and his wife, the former Doña Sofia.
…the wedding was blessed by Cardinal Gerhard Ludwig Müller, a German cardinal of the Catholic Church.
The newlyweds, who met in Sicily, announced their engagement in May and the new Duchess of Noto converted to Catholicism last year in a ceremony at the Vatican.
