Chaim Schlaf, From Wien. - חיים שלאף

I added to document where i took it from, maybe there is a misgake or I read it wrong, have a look.

Nope. You read it correctly. I was going from כנסת יחזקאל, which speaks of his son who was murdered by the Nazis, but I mistook it to imply his only son. Where is your source from?

Someone from the extended family, I dont know who.

Are you connected through the Landau or Schlaff side?

Landau.
You can see how if you press the pin by the relationships on my profile and then go to Chaims or vice versa.

Okay, thanks.
