Her father died in 1845, and her mother, Marie, married Prince Anthony of HatzfeldtTrachenberg in 1847. By this marriage, the economic situation of mother and daughter, which until then had not been comfortable, was improved due to the wealth of Hatzfeldt. von Schleinitz was trained as a pianist from her early youth taught by such virtuosos as Carl Tausig, she developed a remarkable musical talent. Her acquaintance with Franz Liszt, who also showed interest in the advancement of her musical abilities, dates from this period.
