Jacques Littmann

My grandfather told his family had a very large printing and Berlin that his father had been poisoned by lead of the inks used.In 1936, his mother sent him with a fake Polish passport to America to escape the war. He came to Argentina without knowing the language and underage. He was 10 years without knowing anything about his mother and sisters, until the red cross, he learned that they were alive and living in Holland.He was reunited with them, were in contact until the day of his death on July 20, 1990, was 72 years old.I would like to know more about their history, their parents, their sisters. I think Ursula (Uschi Rubinstein Littmann) could be alive in Holland - Amsterdam.Best RegardsBárbara Littmann
