Marguerite de La Rocque, wife of a French nobleman, accompanied her husband on a expedition to the New World. But in 1542, when he discovered that she was having an affair with a crew member near the journey's end, she was cast away on Harrington Island off the coast of Canada, joined by her young lover and a maid-servant. She gave birth to a child soon after, but was eventually subjected to solitude after the baby perished, and with it, her two companions.
Le Rocque remained alone on the island for years, hunting the island's wildlife until she was picked up by passing fishermen and returned to civilization. Eventually, she made her way back to France and published a book about her experiences.
