Irma's 1928 marriage certificate gives her month of birth as July, whereas her birth certificate gives June. This appears to be an error in the marriage certificate. The marriage was witnessed by Louis Pinkus; both had the same address in Breslau, Nachodstrasse 13. Louis was aged 51 years so born 1876-77. The address is that given in the Breslau synagogue community address list (ca 1930) for Louis and Rosa geb. Nothmann.

Kurt and Irma lived in Breslau at Kuerassierstrasse 19 in ca 1930. They emigrated to the USA, arriving in 1941, having previously lived in Havana.
