In my view, the story of the Cavendishes, with its background of wealth and glamour, scandal and disgrace, is one of the most fascinating of all that have come to light from the 'Titanic' so far.
Anybody with even a passing interest in the couple should Google 'Siegel-Cooper' which will immediately pull up quite an extensive amount of information about the landmark New York department store of that name, which was owned and operated by Julia's father, Henry. There are various photographs on-line from both the turn of the century and the present day - it was, and remains, a vast and magnificent edifice, which in its heyday rivalled both Macys and Harrods. Evidently, it was a great money-spinner too; the profits made Henry hugely rich and allowed his wife and daughters to move in the highest social circles and contract marriages with members of the European aristocracy. I seem to recall reading on another thread that, whilst on the '
Carpathia', Julia Cavendish and Leila Meyer (the daughter of the proprietor of Saks Fifth Avenue who had also been widowed) offered guarantees to Second Officer Lightoller that he could be kitted out at their family stores, free of charge, upon arrival in New York. A touching gesture.
I'd also add that a book I've mentioned on the board before, 'Crowning Glory: American Wives of Princes and Dukes' by Richard Jay Hutto, contains a lovely portrait, circa 1910, of the Italian Count Carlo Dentice de Frasso, who Julia's step-sister, Georgine Wilde, married at Brompton Oratory, London, in the spring of 1906 (Julia was a bridesmaid). As Brian points out in his post above, the marriage was dissolved in 1921, and the Count was later married again, to a very interesting lady called Dorothy Caldwell Taylor, who blazed a trail in international high society during the Jazz Age and even (reputedly) inspired a character in Clare Booth Luce's scandalous - and delicious - play, 'The Women'!
