Magdelaine was born to the Lévesque family, affiliated with the Templars since the Third Crusade. One of her relatives, the French merchant Marie Lévesque, took part in Templar plots during the French Revolution thirty-five years later.
In 1747, Lévesque sent a letter to Madeleine de L'Isle, recognizing her handling of her father's business, integration into the upper echelons of New Orleans society, and her discovery of the Templar Order. Lévesque offered her a position within their ranks, and tasked her with finding something of immense value beneath the ancient Mayan structures in the Yucatán Peninsula in Mexico.
