The Full Timeline: Marie-Anne Thiébaud’s Age, the Betrayal, and the Aftermath
Marie-Anne Thiébaud was born in Switzerland in 1970. By the time her path intersected with global music royalty in the late 1990s, she had married Frédéric Thiébaud, a rising Swiss business executive who spent years directing international operations for food and beverage conglomerate Nestlé. The couple lived comfortably within the upper-middle-class enclave of the Swiss Riviera, centered around Lake Geneva.
Twain and Lange had purchased Château de Sully, a sprawling 46-room estate in La Tour-de-Peilz, seeking refuge from invasive media scrutiny. The compound required round-the-clock logistical oversight, and Twain hired Marie-Anne to run the property. What started as administrative management grew into deep personal proximity. Thiébaud handled household finances, organized travel itineraries, and served as Twain’s day-to-day companion while Lange spent exhaustive stretches working in his private recording studio. Because both women were raising young children in the same corner of Switzerland, Twain’s son Eja was born in 2001, and the Thiébauds shared a daughter, Johanna, their domestic lives intertwined completely.
Twain considered Marie-Anne her closest friend on European soil. They traded family recipes, spent holidays side by side, and confided in one another about marital vulnerabilities. That proximity proved catastrophic when Lange abruptly declared in early 2008 that his marriage to Twain was over.
