The September 18 1929 edition of the Toronto Daily Star had a photo of an English peer who was dropping in on America for a visit:
Lord Charles Arthur Francis Cavendish (1905-1944), to give him his full name, might have been coming to America to do more than pay a visit – he was in the process of getting hitched to Fred Astaire’s sister, Adele Astaire. She had been performing with her brother for 27 years, and gave it up to become Lady Cavendish in 1933.
When the couple got married, they received Lismore Castle as a wedding present from Lord Charles’s father, the ninth Duke of Devonshire; this is one heck of a starter home! Despite this favourable start, their lives were marred by tragedy: she gave birth to a daughter in 1933 and twin sons in 1935, and all three lived only a few hours. Lord Charles himself was an acute alcoholic, which claimed his life in 1944.
Lord Charles’s will stipulated that his widow was to inherit the castle, but that it was to go to his nephew if she married again. She did indeed marry again – but, according to her Wikipedia page, she spent summers at the castle until the end of her life. She never returned to the stage, and she passed away in 1981.
