Here is some more info on my family: my grandfather Leo Ratner changed his name to Ratner before coming to this country. Other relatives that followed also took the name Ratner, and I know of no Charles. Leo's name in the old country was Varencove. Other variants I have heard are Warencof and Warren.
I have made contact with some descendants of Paul since I posted this message. And I have also discovered the two names missing from the list of children I posted are Abraham/Alan and Sam.
