In the Gani Ester cemetery in Rishon Lezion there is a tombstone for the grave of Frida Loyfer (daughter of Haim and Mela), who died on April 5, 1985.
Considering the identity of the father’s name, the location of the cemetery and the closeness of the dates, it is likely that the Frida Loyfer buried in the Rishon Lezion cemetery is the same Frida Loyfer whose assets are managed by the general guardian.
