Any surviving heirs of Elsa LUSTIG originally from Nachod, Czechoslovakia

Does anyone here recognize this LUSTIG family from Nachod?

The whole of this family unit perished in Lodz and in Auschwitz, and I am wondering whether any uncles or aunts survived....

Bernhard GUTTMANN, a merchant in Tabor, married Sara  BENESOVA
Their daughter Elsa Eliska GUTTMANN  born 27 Aug 1881 married Hugo (Hugon) LUSTIG  born 1879
 (did either of them have siblings?)

They had a daughter (were there any other children?):
Anna LUSTIG born 22.January 1909  who married Zdenek BRILL born 4 Dec 1903
Their children:
             Pavel (Paul) BRILL
             Jindrich (Heinrich) BRILL (born 30 Mar1931)
             and Helena  BRILL (born 16 March 1934).

In the course of our search we came across a page of testimony deposited at the Yad Vashem memorial institutse in Jerusalem:

We have now also leared that Rudy Brill has died on March 8th 1996 aged 83.

Can we find his heirs??

Do you recognize any of these people?

Can you guide us in any way?

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