The Woman Who Survived A Shipwreck, Starvation, And Isolation — The Incredible Story Of Marguerite De La Rocque
The Counting Of Days
Two and a half to three years.
That is the estimate — based on the available historical sources — of how long Marguerite de la Rocque spent on the island.
The range exists because the sources don’t give precise dates for her abandonment and rescue, and the estimates based on the timing of the expedition and the plausible timing of the Breton fishing voyage that rescued her produce a range rather than a specific number.
Two and a half years is 912 days at minimum.
