The brother of Lady Natasha Rufus-Isaac or Finch (wife of Rupert Finch, ex of the Duchess of Cambridge) who is a designer of some of the Duchess's favourite clothes under the Beulah brand is apparently settling down after dating socialite Davina Harbord of the barons Suffield. Not sure about Olivia Callaghan's antecedents, but the Viscount is the son and heir of the Marquess of Reading, who is great-grandson of Rufus Rufus-Isaac, 1st Marquess of Reading and a Viceroy of India.
