Hi Helen

You should also read what is written on the back of the Brazil immigration card of Mauritz (Mauricio) Popower, there is also a second card where the information on the back continues.
The same for the Brazil immigration cards fo Elza Chmielnik, née Popower, and Lajb Chmielnik, he has three immigration cards, where the information on the back continues.

If they immigrated to the United States before 1957 and if they arrived in New York, you could find their passenger manifest online on familysearch and ancestry.
