Gender: girl
When searching for E. Altman I was able to find Elsa Altman, Ela Altman, Estera Altman, Estera Zygmuntowicz, and Estera Zygmuntowiczaltman. I do not believe that these are all the same person because Elsa Altman was bor on June 18, 1920, Ela Altman was born in 1928, and the othe three girls were born on August 21, 1920.
