From my own research:
Leonora Melania PERTHAIN. Born Leonora / Lea Manzie JACOB.
Known to Cornelia Kraft as Coca (given name).
Born: 18 July 1887, House #735, Dorna-Watra, Bukovina, Austria. Today, Vatra Dornei, Romania.
Died: On or very shortly after 3 December 1941, en route or at Jungfernhof concentration camp, Riga, Latvia. According to Cornelia Kraft, she was "poisoned in train to concentration camp", although that statement is ambiguous as to whether she poisoned herself or was poisoned by another. Kraft gives that same description for the fate of her husband Hermann.
