When Catherine was six years of age, her father died; Catherine and four-year-old Agnes were placed under the guardianship of their paternal uncles, Frederick the Fair and Albert II, Duke of Austria.

At the age of 18, Catherine married her first husband Enguerrand VI, Lord of Coucy, a French nobleman. The marriage contract was signed at Vincennes on 25 November 1338. The marriage produced one son, Enguerrand. The couple were married for eight years when in 1346, Enguerrand VI was killed in battle as part of the Hundred Years' War between France and England. Enguerrand was killed in one of a series of battles which ended with the Battle of Crécy on 26 August 1346. Their son Enguerrand succeeded his father as Lord of Coucy, and he later married Isabella, eldest daughter of King Edward III of England.
