Irén Gábor (Rosenfeld) - Feri & Eva Beretvás

Re https://www.geni.com/family-tree/index/6000000053929286866

If they were just close friends, it is most unlikely for you to prove a tie using the public archives.
The best you can hope for is them appearing on documents as witnesses to a marriage or as god parents to a baptism.

If you feel they could be related in some way however, it is a worthwhile task to further extend both their family tree and yours to see if the two ancestries eventually coincide.

I could not find your tree, so started another, and only later found your duplicate.
It transpires that you have listed Anna and her ancestors as Netti Schimmer and not SchWimmer.
Can you confirm that she and they were all Schwimmers?

I found the link between Irén Gábor (Rosenfeld) and my Grandmother Anna Riesz (born Schwimmer) after I found a death notice for Gábor / Gabriel Langráf, who died on 11 Apr 1900, in a local Papa newspaper. Gabriel Langráf,proved to be the missing link as follows.

Jakob (Jakab) Spitzer b c1818 Komarom m Maria (Mari) Klein b c 1818 Isztimer (NW Fejer county) and had a number of children including Katharina Spitzer, who was my grandmother's grandmother, and Rozália Spitzer who married Gabriel Langráf. This later marriage produced Teréz / Terezia Langraf. Terezia Langraf married Sámuel Rosenfeld and Irén Gábor (Rosenfeld) was their daughter.

I found the death notice by searching the archives in the Hungarian National Library.

Congratulations on your find. It looks as though you have cracked it.
