Robert Guérin du Rocher (1736-1792) was one of the Jesuits who were killed when the French Revolution turned into a rabid anti-Catholic persecution. Father Guérin du Rocher, like his brother Peter, left France after the suppression and traveled to Asia Minor, presumably to work as a missionary. He became pastor in Salonika but was eventually expelled by the Turks. On his return to Paris he became spiritual director for the Sisters of the Visitation. He was arrested with his brother in the house for new converts.
