She was a French noblewoman, heir to lands in Périgord and Languedoc, a woman who had been raised in the comfort and order of the French aristocracy.

The year was 1542.

The island was remote beyond any convenient description — not simply far from cities but far from any human presence at all, a cold rock in a cold sea where European settlement was almost entirely absent and the nearest Indigenous communities were nowhere near enough to offer hope.

The reason she was being abandoned is a matter of historical debate.

What is not debated is the outcome.

She survived.

Not just survived in the minimum sense of enduring until rescue arrived.

She survived conditions that killed the people who were with her.

She survived an Arctic winter on an uninhabited island.

She survived grief and loss and hunger and cold and isolation of a degree that most people who have ever lived will never encounter.

And then she came home.

And she told her story to at least one person who wrote it down.

This is the story of Marguerite de la Rocque — not the embellished version that later writers would construct, not the dramatic novel or the political allegory, but the documented core of one of the most remarkable survival accounts of the sixteenth century.

Why “Should Have Killed Her” Is Not An Exaggeration
