She was alive when the Breton fishermen found her, somewhere between 1544 and 1545.

In between, the following happened: she was placed on an uninhabited island in the Gulf of St.

Lawrence with limited supplies and no prior training in wilderness survival.

Three people — her companion, her nurse, and her child — died while she was on that island.

She was alone for an extended period.

The winters of the Gulf of St.

Lawrence are cold enough to kill an inadequately sheltered person in days.

She is on one side of all of those facts.
