czy to jest osoba opisywana w wiki jako studentka muzyki, którą poślubił brat Franza, Ferdinand, i która wcześnie zmarła?
'Four years later, in 1816, he [Ferdinand] was promoted to full-time teacher at the orphanage. In that year, [Ferdinand] Schubert married one of his students, Anna. [...] After his first wife had died, Ferdinand married his second wife, Therese, in 1832.'
Wiem, że nie jest to specjalnie uniwersyteckie źródło, ale na start zawsze jakiś punkt zaczepienia...
