The third girl, Caroline also knew Beethoven, but she married to Count Imre Teleki at a very young age and lived the rest of her life in Hosszúfalva. Her first-born daughter, Blanka founded the first Hungarian boarding school for girls. After the fall of the 1848-49 Revolution and the War of Independence, the imperial court sentenced her to a 10-year imprisonment in a castle because of hiding outlaws and issuing ‘rebellious articles’. After years in Kufstein, she was taken to the fortress prison in Laibach, from where she was released with amnesty in 1857. She no longer returned to Hungary and died in Paris, and was buried there.
