For some survivors of the Holocaust, the vow to "never forget" takes on a special meaning when they have only faded memories, or none at all, of parents they lost as young children.<br /><br />Leah Nebenzahl was a baby when her parents, Pipha and Zvi Herschman, were murdered in Nazi-occupied Poland.<br />The Jewish infant, rescued by a priest who placed her in an orphanage run by nuns, survived World War Two as the adopted daughter of a Christian couple.<br /><br />On Wednesday, Holocaust survivors mark the 76th anniversary of the liberation of the Auschwitz death camp by Soviet troops.<br /><br />The stories and photos of Jewish youngsters, some of them orphans like Leah who were placed in seven children's homes for survivors in Europe after the war, are part of a new online exhibition - "My Lost Childhood" - by Israel's Yad Vashem Holocaust museum.
