Haydn wrote to Mrs. Genzinger often, expressing his loneliness at Esterháza and his happiness for the few occasions on which he was able to visit her in Vienna.
Haydn kirjutas Genzingerile tihti, väljendades oma üksildust Esterházas ja oma rõõmu nendest mõnest korrast, kui ta sai Genzingeri Viinis külastada.
