On 17 July 1935, Whitney married Lady Daphne Finch Hatton at St Margaret’s,Westminster.
Daphne wore a striking dress of heavy silver lamé with long train, and a head dress fashioned in the shape of a crusader’s camail from silver net sewn with orange blossom. Much like his biographer 54 years later, Whitney was clad in black frock coat, grey trousers, pale waistcoat, wing collars and cravat.
One guest at Whitney and Daphne’s wedding had just quit a career as a banker to try stockbroking.
