Family of Valtr FRANKFURTER

We are NO LONGER searching for the legal heirs of Valtr ( Walter) FRANKFURTER born 20 June 1923,
 son of Jindrich (Heinrich) FRANKFURTER (born 4 June 1891 in Brno) and his wife Zofie (Sofia Zosia) nee FASTMANN.

Jindrich (Heinrich) FRANKFURTER died in Brno in 1936. Zofie perished in Lwow ghetto in 1942.

We are, therefore, hoping to locate close relatives on the FASTMANN family side.

We believe the family tree is as follows:

1. Gedalje FASTMANN
sp: Hanna KREPPEL (b.17 Dec 1870-Drohobiez,Drohobycz,Lwow,Poland)
        |-2. Zofie Roz FASTMANN (b.11 Feb 1896-Drohobytz,Ukraine d.1939/1949-Ukraine)
        | sp: Jindrich Heinrich FRANKFURTER (b.14 Jun 1891-Brno d.11 Oct 1936-Brno)
        |        +-3. Walter FRANKFURTER (b.10/20 Jun 1923-Vienna? d.17 Sep 1942-Auschwitz)
        |-2. Gedalije FASTMANN (b.23 Jul 1866-Drohobytz,Ukraine)
