Edith Marie Van Buren (1858–1914), also known later in life as the Countess de Castelmenardo, was an American socialite and world traveler.
She is remembered for her tourism in the Yukon, her contentious divorce from a man styling himself as the Count di Castelmenardo, and her family connection to Teaneck, New Jersey.
Harriet Sheffield's brother-in-law, William Walter Phelps, encouraged the family to take up residence in Teaneck, New Jersey.
[5] In 1898, Van Buren went to Klondike with her friend Mary Evelyn Hitchcock, embarking from San Francisco on a steamer.
Wishing to legalise her married name and secure her status, she paid to procure her husband a genuine title of nobility, then learned that he was committing adultery.
