You should know that during a part of the wreck The Frank family kept hidden along with another family, until they were captured and taken to the concentration camp. Here's what happened to each of them at the end of the war:

In the winter of 1944 the Russian army is advancing and gaining ground. The Nazis decide to take as many prisoners as they can who are still qualified to work for Germany. The health of women prisoners is a priority. Edith FRank can not go. Margot and Anne are considered fit. In late October or early November 1944, Margot and Anne Frank are huddled into a crowded freight train bound for the Bergen-Belsen concentration camp, Edith Frank is left behind at Auschwitz. She falls ill and dies on January 6, 1945. After a horrible three-day trip, Margot and Anne Frank arrive in Bergen-Belsen. More and more prisoners are being sent from other concentration camps to Bergen-Belsen. The field is already too full when their transport arrives there, so the new women are put into tents. A few days later the tents are destroyed by a huge storm. These prisoners then have to find space in one of the already overcrowded barracks.  In the winter of 1945, the situation in Bergen-Belsen worsened. There is little or no food and the sanitary conditions are terrible. Many of the prisoners get sick. Margot and Anne pick up typhus. They both die just a few weeks before the camp is released. In late November 1944, another convoy carries prisoners from Auschwitz to Bergen-Belsen. Auguste van Pels is probably also among those prisoners. She is reunited with Margot and Anne again. However, after a few months she must leave Bergen-Belsen again and be taken to Raguhn, which is a part of the Buchenwald concentration camp. From Raguhn she is sent to the Theresienstadt camp. During the voyage, between April 9 and May 8, 1945, Auguste van Pels is murdered, it is unknown how. Regular selections were made: prisoners who are too ill are sent directly to the gas chambers to be killed. A few weeks have passed since his arrival, and Hermann van Pels, exhausted, is no longer fit to work. It is selected and then gassed. Just before their liberation, the Nazis evacuate the concentration camps. The prisoners who could still walk were to go with them. Peter van Pels was among those prisoners. He arrived at the Mauthausen concentration camp in Austria at the end of January. The prisoners were forced to do heavy work. Peter van Pels probably died between April 11 and May 5 due to exhaustion. Fritz Pfeffer was deported to the Neuengamme concentration camp in October 1944. Thousands of prisoners die there due to a combination of heavy work, food shortages and poor sanitation. Fritz Pfeffer is one of them. He died at the infirmary barracks on December 20, 1944, at age 55. On January 27, 1945, the Russian soldiers liberated Auschwitz. Otto Frank is one of the 7650 prisoners still alive, being the only member of the Frank family and the residents of the secret annex that survived the Holocaust.

The answer is professionals such as attorneys.
