We just found the passport that my grandfather's brother used to travel
from Poland to Argentina in august 1921. Those this means he had polish
citizenship or could it be just a travel document?
He was born in Polonnoye and fled the ukranian shtetl when her mother
was killed in a pogrom around 1919.
