Étienne Guibourg

The Abbé Étienne Guibourg (c. 1610 – January 1686) was a French Roman Catholic abbé who was involved in the Affair of the Poisons.

He was the sacristan of the Saint-Marcel church (destroyed during the French Revolution^[1]) at Saint-Denis, and formerly the chaplain to the Comte de Montgomery. He claimed to be the illegitimate son of Henri de Montmorency. He had a long-term mistress named Jeanne Chanfrain, with whom he had several children.

In 1680 Françoise Filastre, under interrogation in connection with the poison affair, claimed that Guibourg had performed Black Masses for Catherine Monvoisin around 1672-3. Guibourg was arrested and confessed to this and other crimes. He was sentenced to life imprisonment and sequestration and died in prison in 1686.
