Oisie = Osie?
is It Yiddish for Yosi / Yosef? is it Yehoshua?
There is a match for Osie Weissbuch who probably emigrated to the US.
His wife is called Tillie in the american registrar. Tillie is probably anglicized for Tzilli / Tzilla.
Is it possible that Tzilli / Tzilla is Zelda? interesting.
Osie Weisbuch + Tillie Kuntz
son: Abraham Weiss 1895 - 1963
