Just this evening I found my first Brazilian document. I found the Immigration Card for Renata Steuer in the Brazil, Rio de Janeiro, Immigration Cards, 1900-1965. This not only gives her date of birth, but also her place of birth, Breslau Alemanha.
After finding this document, I decided to do another search to see if I could find any more Brazilian documents. I found another immigration card, this time for Neil Burt Steuer, a geologist, who was born in Cleveland, Ohio. His card had his photo on it.
I continue looking, and another Cleveland born Steuer was found! Irwin Steuer, the son of Joseph and Lillian Steuer, immigrated in 1957. Irwin's card was actually a tourist card. He was married and living in Beverly Hills, California at the time.
I was hoping to find the immigration cards for Renata's brother, Rudolf, and her mother, Karoline (Lina) Bry Steuer. Unfortunately, their immigration cards don't seem to be online. Maybe they will be in the near future.
