“Diana’s great-grandmother Frances Work, or Fanny, as she was known to her family, was an American, and perhaps that is why the Princess always felt such a great affinity for the land across the Atlantic. Fanny’s father began his career as a clerk in Ohio and ended up making millions as a financial whiz in Manhattan. A great patriot, he promised to disinherit any of his offspring who married Europeans. But Fanny, like Diana a strong-willed woman, crossed the Atlantic and married British aristocrat James Boothby Burke Roche, who became the third Baron Fermoy. When the marriage broke up, she returned to New York with twin sons and a daughter, and her indulgent father forgave her.”
