Hitler's 6th cousin also died in the gas chamber.

 German media reported on the 17th that Adolf Hitler's younger sister was found to have been slaughtered in a gas chamber in accordance with Hitler's order to forcibly euthanize mentally and physically disabled people. Germany's Munich Forensic Research Institute and Austria's Oversalzburg Modern History Research Institute have recently discovered new data showing the dark sides of Hitler's household. According to the report, Aloisia V., a two-year-old Austrian-born sister of Hitler, was killed in December 1940 in the gas room of Hartheim Medical Research Institute near Linz, Austria. Aloisia, who was 49 years old at the time of his death, was imprisoned for nine years at a mental hospital in Vienna, Austria, and went through other facilities for a while in November 1940 and was executed on December 6. This is more meaningful than the fact that the Nazis first revealed that Hitler's close relatives were included among the victims of a group murder of 270,000 people with disabilities and mental illness under the name of forced euthanasia. There was word of mouth that Hitler tried to keep his family history secret, said Dr. Timothy Leiback, an American historian who has been participating in the study since last year. "60 years later, the reason Hitler wanted to hide it so much is revealed." Aloisia, who suffered from schizophrenia and depression, usually made crafts peacefully, but often suffered from hallucinations and delusions and destroyed the cross on the wall. The researchers, who discovered 150 pages of new data, said the data did not lead to conclusions about Hitler's mental health, and there was no evidence yet that he suffered from schizophrenia or similar symptoms. However, he explained that the many cases of diseases in Hitler's household suggest the possibility that "abnormal personalities" would have appeared more than usual. Hitler's father's family, including Aloisia, was found to have several mentally ill patients and one suicide. In addition, in the case of the maternal side, her cousin's younger sister and aunt suffered from spinal curvature and dwarfism, respectively, with her waist bent with S. Based on the excavation data, the researchers will publish a book on Hitler's family history, which has not been well known, and Germany's second public ZDF broadcast is preparing for a related program.
