Is there anyone on the list who can help me with the Serbian language?

I am seeking living descendents of a Serbian Holocaust victim family.

Google shows me a couple of possibilities - but I need Serbian, not English

Among the millions of Jews murdered in Auschwitz were Julija Vajs
(Julius Weiss), born 1879 and his wife Karolina Vajs (Weiss) maiden
name Sajnberger, born 1884.
Before World War 2 their home was at Futoska 6, Novi Sad 21000, Serbia.

Thanks for any help you can offer
