Sorry for the confusion. I have an (not quite sure) assumption that
my maternal grandmother came >from Akkerman? near Odessa?.
Maybe I will come to Kamenets sometime .
My paternal family names are Risemberg (Orynin) and Sandler
My maternal family names are Barsky (Ukraine?) and Rochansky
(Ukaine? Odessa region? Akkerman?) )
I also have famliy by the name of Dunayevitch (no contact) . Maybe
thay also came >from your region?
