In 1792 (note: one year before his death?), "Ivan Rattkay (note: i.e. Joseph Johann Nepomucenus) left the Mali Tabor castle to his nephew, the baron Joseph Wintershoffen, in whose possession it remained until 1818, when it was inherited by Rikard Jelačić from the Zaprešić branch. They owned it until 1876, and from then it was owned by the Irish baron Henry Cavanagh."

In fact, the ownership was probably shared between Joseph Wintershofen and the daughter of his 1783 deceased sister Leopoldine Moscon, born Wintershofen. The daughter's name was Leopoldine Kavanagh Ballyane, born Moscon. Later on, the Kavanagh family acquired also the other part of the castle.
