Can you possibly help?

We search for the family of a woman who in her life had occasion to use several pseudonyms:

Nurit ELDAD
Nurit ELDAVID
Nora ELDOC
Nurit DANZINGER

She was born on 12 Dec 1912 and died in Argentina on 23 March 1960

In particular we would like to locate:
Arnold ELDAVID
Gerda ELDAVID
Helga ELDAVID
Iganz ELDAVID
Edith HAMMERSCHLAG nee. ELDAVID
Vera nee. ELDAVID LEHMANN / LIEMAN / LEEMAN
Margarita SANDER nee. ELDAVID    who possibly lived in Lomas del Palomar

Do you recognize any of these mames or facts?

Can you guide us in any way?

If you have no information, do you know of anyone else, anywhere, where we can ask?
