Thérèse de Couagne

Thérèse de Couagne (1697 – February 26, 1764) was a knowledgeable business woman who played an active role in the New France economy.

Thérèse was married to François Poulin de Francheville in 1718 and became a widow in 1733. She became interested in business after her husband died.

She was also the owner of the slave Marie-Joseph Angélique. It was this slave who while trying to cover a planned escape, set fire to the widow's house in 1734. The fire burned out of control destroying much of the settlement of Montreal.
