She received music lessons from Franz Schubert during the summers of 1818 and 1824 on her family estate at Zseliz (today Želiezovce).

On 8 April 1844, she married Count Karl Folliott de Crenneville-Poutet,[6] but the marriage broke down within a few months and the couple separated.

[7] Schubert's friends believed him to be in unrequited love with the young countess, and there are a number of references to this in their writings.

[8][9][10] Eduard von Bauernfeld wrote of his friend: "He was, in fact, head over heels in love with one of his pupils, a young Countess Esterházy [...].

[...] On such occasions Schubert was quite content to take a back seat, to remain quietly by the side of his adored pupil, and to thrust love's arrow ever deeper into his heart.
