Another great-grandson was the founder of the Polish historical study of literature Ignacy Chrzanowski (1866–1940), who died during the Sonderaktion Krakau at Sachsenhausen concentration camp. His son Lieutenant Bogdan Chrzanowski was murdered by Soviet soldiers, on the expressed orders of Joseph Stalin, in the Katyn massacre. His daughter Hanna Chrzanowska is being investigated by the Catholic Church for possible sainthood. The council of cardinals in Rome has decreed that she has practised the cardinal virtues of Faith, Hope and Charity to a heroic degree and, therefore, may be referred to as Venerable Servant of God.
