A Walter Bartenstein, businessman last resident in Ratibor aged 29 years (so born 1892-93) sailed from Hamburg to Santos, Brazil in 1922. In 1942 a Walter Bartenstein, widow, born 01.08.1893, a businessman last resident in Germany, son of Siegfried and Frieda, registered in Brazil. I suggest that these are the same person, and that he is the sister of Irma, who had also emigrated to Brazil in 1939.
