George, Duke of Saxony
In 1464, the manor of Pakosław (Greater Poland) was bought by one Johannes Brühl (senior), whose son Johannes Brühl (junior) left Poland for Saxony in 1496 with his wife Balice Banarowna, heiress of Oświęcim, accompanying the king's daughter, Barbara Jagiellon (later the wife of George, Duke of Saxony). The name Brühl-Oswiecino was still in use into the 18th century.
