My Grandfather Barnett Kubel was born 9th May 1880 in Warsaw. I know he was conscripted to the army to fight in the Russian/Japanese war and then went to London, married, had a daughter, then a son my father Harry who is 85. I know that Barnett had a brother, Isaac and a sister Rosa in London. I know very little about another sister who went to America. They spoke Yiddish and used there Yiddish names.
