Charles de Beauharnois (1670–1749).
Beauharnois was the Governor of New France from 1727 to 1746, when he was replaced
after the loss of Louisbourg to the British. In 1743 he gave a commission
to Louis Fornel to explore the Baie des Esquimaux, and Fornel subsequently named
a large island "forming the southern entrance of the bay ... pointe de Beauharnois".
