I'm the grandson of Adolfina (Doba) Chameides whose brother Edward (that you called Jacob - but we are 100% sure of his mae) married Chana Adler, and had two daughters. I have checked all data in various sources, including JewishGen.
It seems Chana is called Hania in your tree but also has different parents (Bernard and Klara vs Markus and Chaje). The siblings names can be different as people had Jewish names and secular names (I based myself on birth certificates I found in Jewish Gen).
I was not aware Chana had remarried but it is probable as her husband died young.
I am concerned about merging more data, as I am not sure which data is correct and I am not a member of the Adler family.
Any help from @Victor Lipinski or anyone else would be appreciated.
Yours
Alain Herz
