Most people are unaware of Hitler's WW1 relationship with a 16 year old French girl named Charlotte Lobjoie from 1916-17. She had a son in March 1918 and did not list the father as he was a German soldier. By 1922, she married and her son, Jean-Marie Lobjoie took on her husband's last name of Loret. Hitler's valet revealed that Hitler thought he had an illegitimate son and by May 1940 had her sought out by the SS. She was paid by the German Army throughout WW2 and her son was interrogated by the Gestapo. After that, he became a French policeman used by the Germans. By 1948, postwar, his mother revealed to him that Adolf was his father. He married several times and had 9 children! He wrote about his father in a book and died in 1985. He had matching blood type and bore a resemblance to his father. His family and history experts have tried to claim this is a pure hoax, but scientists agree that Lerot may be Hitler's son. Based on the information above, we at least know she had a sexual relationship with him (claimed alone) and then gave birth. His valet confirmed his belief he had a son and there are records of Hitler's payments to her during WW2. I have no personal opinion on the subject.
